Introduction Git is a powerful version control system that helps developers track changes in their code. Sometimes, you may commit changes accidentally or realize that you need to undo them. That's where git reset comes in. The git reset command allows you to undo commits at different levels: --soft - Keeps changes in the staging area. --mixed (default) - Unstages changes but keeps them in the working directory. --hard - Discards all changes completely. In this guide, we'll explore each option with examples, use cases, and tips to help you undo commits effectively. git reset --soft - Keep Changes Staged This option moves the HEAD pointer to a previous commit but keeps all changes in the staging area(index). git reset --soft HEAD~1 This undoes the last commit but keeps the chang…  ( 7 min )

Purpose In a world where software must evolve or perish, we embrace a principle often overlooked: The value of things that are designed to disappear. Ephemeral Design is a mindset that encourages developers to build systems with impermanence in mind—favoring modularity, replaceability, and minimal long-term baggage. Favor deletion over preservation. Design with a clear exit strategy. Ephemeral Design Manifesto Be honest about what might disappear. Optimize for change, not permanence. Practice Hints Modularize everything: small parts are easier to remove or replace. Isolate experimental features from the core domain logic. Document the lifespan of components, especially if temporary. Avoid over-engineering for uncertain features. Use structure or conventions to indicate ephemerality (e.g., separate directories, metadata, flags)—but balance clarity with elegance. Adopting Ephemeral Design doesn’t mean building carelessly. intentionally, with the courage to discard what no longer serves. Teams that embrace this mindset: Move faster by reducing fear of technical debt Feel safer experimenting and iterating Write more honest, sustainable software Everything is temporary—especially in code. By designing with this in mind, we create systems that are not just flexible, but free.  ( 3 min )

💭 "AWS has 200+ services. How do I remember or use them?" That was me — during my college days, opening the AWS Console for the very first time. It felt like IRCTC with jet engines: options everywhere, nothing made sense. So, I did what most students do — I closed it. 😅 But here’s the secret: AWS isn’t scary if you learn it like an Indian story — with chai, analogies, and use cases that click. AWS in Desi Terms Think of AWS as the Tata Group of Technology.

Integrating eSignatures into your app can transform the way users sign contracts, allowing them to do so without leaving your platform. The question is: what’s the best way to integrate a service like BoldSign? Two popular tools dominate the scene: REST APIs and SDKs. Think of a REST API as a universal mailbox.

Article Source: https://juejin.cn/post/7296076144448618506 To further enhance our internal network security, we added the open-source community version of SafeLine WAF on top of our existing hardware WAF as a software WAF at the application layer. This enabled a multi-layered WAF protection architecture. After further exploration, we found that SafeLine WAF's upstream proxy forwarding is based on Tengine. This gave us the idea to use SafeLine not only for WAF protection but also for load balancing and automatic failover. We created a simple HTTP server with a /status route returning HTTP 200. Here's a basic Go example: package main import ( "os" "fmt" "net/http" ) func Hello1Handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "I am 11111") } func Hello2Handl…  ( 4 min )

If you've ever translated a document packed with formatting—think footnotes, side-by-side columns, tables, or scanned images—you probably know how quickly it all unravels. Headers vanish. Tables lose their shape. Footnotes crawl into random paragraphs. That’s exactly the kind of mess I ran into. So I started looking for tools that could handle translation and document fidelity—without turning everything into plain text soup. Most tools claim they "support documents" but here's what usually happens: Footnotes get merged with the main body Tables collapse or turn into basic text Fonts and headings lose their hierarchy PDFs with scanned images become unreadable And if your document has two columns, custom fonts, or embedded elements? Most services just aren't built to handle t…  ( 5 min )

In modern software architecture, real-time communication between systems is a necessity. And Webhooks have appeared as a simple and effective method for applications to get updated information from other services instantly. In event-driven systems, it's more important due to the need of responsiveness and automation. A webhook is used to send information from one system to another, in real time, as soon as a particular event happens. Rather than checking with an API at certain times, a webhook allows the source system to send data right away to a predetermined location. For instance, you can use a webhook from Stripe so your application is informed when a payment is successful or unsuccessful. Thanks to this, you can make updates in real time to the order status, send emails or retry logi…  ( 5 min )

GitHub Actions usage reporting doesn't tell the full story. If you're running different types of runners (like 4-core, 8-core, or more), those minutes aren't equal, and your total usage number doesn't reflect it. This guide will show you how to: Export your raw usage data Normalize it by runner type Get an accurate total you can actually budget against \ Why normalizing GitHub Actions minutes matters Runner types in GitHub Actions have different compute capacities and costs. For example, a 4-core runner can do twice the work of a 2-core runner. If you just sum the raw usage, you're underestimating your real consumption and leaving yourself open to surprise bills. Step 1: Export your usage report In GitHub, click your avatar (top right) and go to Settings Select Billing and plans Under Usage this month, click Get usage report Choose your date range (30/60/90 days) and download the CSV You'll now have a CSV showing runner types, quantities, and costs. Step 2: Normalize your minutes Open the CSV in any spreadsheet tool. Focus on the 'sku' and 'quantity' columns. Each runner type has a multiplier based on its compute capacity: Runner Type Multiplier actions_linux 1 actions_linux_4_core 2 actions_linux_8_core 4 actions_linux_16_core 8 actions_linux_32_core 16 To normalize your total usage: For each runner type, multiply the quantity by the multiplier Sum these normalized values across all runner types This gives you the total compute-equivalent minutes your team used during the period. Step 3: Use the data to control costs Without normalized data, you're likely underestimating usage. This normalization process gives you a real number to track, budget against, and compare over time. Take it further with Depot Once you know how many minutes you're actually burning, the next step is cutting them down.

Introduction When I began my ROS2 integration project, AppArmor wasn't even on my radar. My background included years of experience with RHEL and Oracle Linux, and I had developed a solid understanding of SELinux. Initially, I attempted to make ROS2 work on Oracle Linux, expecting a straightforward integration. However, after several days of troubleshooting and configuration tweaks, I was still encountering persistent issues. Next, I shifted my focus to using SELinux on Ubuntu. Unfortunately, this too presented complications that weren't worth resolving at the time. Although both SELinux and Oracle Linux theoretically support ROS2, the practical reality was too time-consuming to justify. On the other hand, I knew that AppArmor was the default MAC (Mandatory Access Control) system on Ubun…  ( 5 min )

🧩 What is KMSPico? At its core, KMSPico is a Windows and Microsoft Office activator that uses Microsoft’s own Key Management Service (KMS) protocol to simulate a local activation server. Imagine this: instead of calling home to Microsoft to verify a license key, your PC talks to a fake KMS server running on your machine, which then tells the OS or Office that everything’s legit. That's KMSPico — a neat little tool that uses corporate licensing logic to activate software on individual machines. Microsoft introduced the KMS system for volume licensing. It was never intended for individuals. Companies that deploy Windows to thousands of machines can’t enter product keys one by one — they need a central activation server that authorizes all devices on the same network. Here’s where KMSPico…  ( 5 min )

A few days ago, I discovered a problem. Although the official Progress bar component of HarmonyOS, Progress, offers relatively rich functions, sometimes it still fails to meet the development needs. For instance, sometimes I need to have a dot on the Progress bar to control the progress. Progress doesn't offer this style, so today I'll share with you the implementation process of a custom progress bar. Here, I use a cascading layout, layering the total length part of black and the white part. The straight lines and dots in the white part are arranged horizontally. When the progress changes, only the length of the white straight line part needs to be modified, and the dots will automatically follow and move. Then add a drag gesture to the dot. In this way, a progress bar with dots is compl…  ( 3 min )

Summary Introduction Context First Example Second Example Third Example This short article aims to help beginner and curious users understand a simple approach to using AI effectively. First of all, I'm not an AI expert, just someone who's curious about it and wants to help others make use of it. I'm doing this for fun, but I hope it ends up being helpful to someone out there! Most sources emphasize that you need to provide context when asking AI questions to get accurate answers. However, what many don’t mention is that you can actually ask the AI itself what context or background information you should include to improve the quality of its response. This way, even if you’re unsure what details are relevant, the AI can guide you on how to frame your request for the best possible resul…  ( 5 min )

Hoje, depois de um dia puxado, me peguei pensando nos pontos que mais me marcaram do livro Team Topologies, do Matthew Skelton e Manuel Pais. Já tinha ouvido muita gente recomendando, mas confesso: só agora lendo com calma entendi o real impacto disso na nossa forma de trabalhar. E olha… como Tech Lead, foi impossível não revisitar cada decisão de estrutura que já ajudei a desenhar. Sempre acreditei que tecnologia é meio, não fim. Mas o livro mostra que como a gente organiza os times importa tanto quanto a stack ou a arquitetura. Sabe aquela história da Inverse Conway Maneuver? De projetar a estrutura pensando na arquitetura que você quer alcançar e não aceitar que a arquitetura reflete os silos que existem? Isso ficou martelando na minha cabeça.

Will AI Replace Developers? Here Is What Is Actually Changing Every week, there is a new headline about AI replacing jobs. Most of the time, the focus is on roles like data entry, customer service, or warehouse work. But what about developers? Will tools like Copilot, Cody, or GPT-4 automate us out of our careers? Let us take a clear look at what is actually happening. AI tools like GitHub Copilot and ChatGPT are very good at specific technical tasks. For example: Writing repetitive or boilerplate code Translating between programming languages Generating unit tests and documentation Refactoring small functions Explaining complex code in simple terms If your day-to-day work involves these types of tasks, AI can already help, and in some cases, replace that part of the workflow.

At this point, I am feeling very confused. I wanted to be a developer, pursued Computer Science since high school but ended up in a network engineer role (thanks to the recession, I had to accept this offer that listed Python and SQL in the job description). I’ve been promising to get into development work for a long time (one and a half years), but no such work has been assigned so far. Now, I’m at a point where I just want to switch job, as my service agreement is about to end. I’m confused—there’s chaos around GenAI everywhere. Should I start with GenAI, or go back to the development work (MEAN stack) I used to do? Due to workload, I could never study consistently for either. I’ve introspected a lot, and I’m still confused. My current job only pays well, but the work is completely disconnected from my career aspirations. Please share your comments, suggestions, and advice.

Ten years ago, learning to code was like unlocking a superpower. Today, it’s still an incredibly valuable skill—but the horizon is shifting fast. We’re entering a new era of software creation, one where the gatekeepers of syntax and stack are giving way to a more intuitive, accessible collaborator: AI. In the future, prompt engineering will be more valuable than programming languages. You will no longer need to "know" how to code—you'll need to know how to think developer-style and be able to clearly explain what you're after to your AI partner. ** Everyone's a Developer Now** Design your UI from a sketch Debug your app in your sleep Optimize backend performance Build full-stack apps by voice Instantly, entry isn't technical ability anymore, but imagination and vision. Designers, marketers, entrepreneurs, and children will create production-quality apps without ever laying eyes on a semicolon. It's already happening. AI-native development environments and tools like Firebase Studio, Stitch, Jules, and Google AI Studio are constructing low-code/no-code platforms powered by high-IQ language models. ** And Professional Developers Then?** Ten-year professionals will focus on: Architecture and system design AI-human workflows for collaboration Security, ethics, and responsible AI adoption Working with code as a tool, not an impediment, to fix actual-world problems The keyboard will not perish—but its role will evolve. Instead of writing out every function by hand, devs will instruct AI agents, generating higher-level abstractions more quickly and with more impact. ** Programming Becomes Human Once More** Coding was once a gift of the elite. AI will make it a creative language of the masses. ⚰️ So, Is Coding Dead? So here's to the future— R.I.P. manual coding. Long live creative engineering.  ( 4 min )

In this post, I’ll show how I fused the latest .NET 10 features with ChatGPT/Azure OpenAI to create a responsive AI assistant in a real-world business app. Why This Topic Works: Combines the hype of AI with the stable release of .NET 10 Shows real use case → "weekend build" makes it accessible and engaging Blends practical code, dev experience, and cool tech — a winning formula What I Built: A lightweight internal tool that allows users to: Ask natural-language queries about enterprise data Generate business reports using OpenAI GPT Summarize customer feedback from SQL data Draft internal documents and emails from structured input Tech Stack: .NET 10 Web API ASP.NET Core Blazor (for UI) Azure OpenAI GPT-4 Entity Framework Core Serilog + Seq for logging Redis for caching prompts Features Used from .NET 10: Minimal APIs v2 → rapid endpoint setup JIT Compiler Boosts → snappy performance under load Span enhancements → optimized string handling for GPT responses C# 14 Field-Backed Properties → cleaner data models System.Text.Json improvements → faster prompt & response serialization ChatGPT Integration: var response = await openAiClient.GetChatCompletionAsync( new ChatCompletionRequest { Model = "gpt-4", Messages = new List { new ChatMessage("user", "Summarize customer reviews from last week"), } }); Tip: Always cache frequent prompts with a smart key (e.g., user + time + intent). What I Learned: Prompt engineering is half the battle. ASP.NET Core is incredibly fast for AI-backed endpoints. .NET 10’s performance gains are visible when batching API requests. Clean architecture + AI = readable, testable, maintainable. Ready to Try? Want the GitHub repo, tutorial series, or free starter template? Drop a comment!  ( 4 min )

✅ What is Pre-Caching? Pre-caching refers to the process of loading and storing specific data or resources into cache before they are requested by the user or system. It is a proactive caching strategy designed to improve responsiveness and reduce latency. Rather than waiting for a user to request something and caching it after that (lazy caching), pre-caching anticipates what will be needed and loads it ahead of time. Improves Speed & UX: Ensures instant availability of key content or features, especially during initial app or page loads. Reduces Latency: Data is ready in the cache, eliminating delays caused by network or server access. Offline Support: In progressive web apps (PWAs), pre-caching allows apps to function even without an internet connection. Reduces Server Load: By servin…  ( 4 min )

By Mohamed Farah Tahar Introduction Adversity is a universal experience. Whether personal, communal, or national, hardship is inevitable. But what separates resilient individuals and nations from those who falter is not the absence of difficulty—but the ability to extract wisdom, strength, and growth from it. In Africa, where challenges span from economic instability to climate shocks, the ability to transform adversity into opportunity is not just an option—it’s a necessity. Reframing the Narrative of Hardship Too often, difficult times are viewed solely through a lens of loss. Yet, every hardship carries within it a hidden lesson, a deeper meaning, or a new beginning.

Cloud adoption is exploding. In 2024 alone, global public cloud spend topped $675B. But scale brings complexity — and complexity breaks. So what happens when your infrastructure breaks? If your DR plan is still a few backup scripts and tribal knowledge, this post is for you. Let’s talk disaster recovery (DR) from a DevOps/Infra-as-Code (IaC) perspective — what it should look like, and how to make it part of your daily workflow. Cloud Business Continuity = Keep things running Disaster Recovery = Recover fast when they don’t If your Terraform codebase is the source of truth, then cloud DR is your ability to rebuild infra from code, not just restore data blobs. Here’s what’s at stake: 💸 Downtime = lost revenue (esp. for e-commerce & SaaS) 🧠 Broken infra = dev productivity loss + missed SLA…  ( 5 min )

"Work smart, not hard!" You hear and read it everywhere. Everyone loves to say it. Why? Because it makes them sound intelligent. And everyone loves sounding intelligent. It gives them a quick dopamine hit that lasts maybe seven seconds, but hey, that's enough to feel amazing for a moment. This advice is especially popular in our field — software engineering. We're problem solvers, right? We love puzzles, we adore challenges. But more than that, we love solving them in smart, elegant ways. That's basically our job to find smart, efficient solutions to complex problems. And I'm 100% on board with that. This is still the worst advice you can give to anyone.

Hey everyone! 👋 New to dev.to and loving the vibes already. I'm on this exciting journey exploring the intersection of code and design. Just discovered Martin Lorenz's work on flexible visual systems and I'm completely fascinated. Feels like a beautiful approach to creating meaningful design systems in an age where AI can pump out content so quickly. Inspired by his approach, I built this little prototype: https://codepen.io/spaghettifunction/pen/myJEoYo It's a grid system where each cell responds to mouse interaction while influencing its neighbors. Nothing groundbreaking, but it felt magical watching those simple rules create complex, beautiful behaviors. Systematic thinking meets creative expression Simple rules creating complex emergent behavior Interactive design that feels alive, not static For those familiar with generative/systematic design: Who else should I be exploring? Any favorite examples of flexible visual systems? What draws you to this intersection of code + design? Still very much learning and would love to hear your thoughts!  ( 3 min )

How to Start a SwiftUI App in 2025 Starting a SwiftUI app in 2025 means embracing the latest Swift and Apple technologies to build modern, fast, and maintainable iOS applications. Whether you’re a beginner or updating your skills, here’s a step-by-step guide to get your SwiftUI app up and running. Install the latest version of Xcode from the Mac App Store (Xcode 15 or newer). Make sure your macOS is updated to support the latest Xcode. Familiarize yourself with the Swift 5.9+ language features introduced recently. Open Xcode and choose "Create a new Xcode project." Select "App" under the iOS tab. Name your project (e.g., SwiftShelfApp). Ensure "Swift" is selected as the language and "SwiftUI" as the interface. The main entry point is marked with the @main attribute. Your ContentView.swift uses SwiftUI’s declarative syntax. Learn the basic building blocks like View, State, Binding, and ObservableObject. Start by modifying ContentView.swift: import SwiftUI struct ContentView: View { @State private var counter = 0 var body: some View { VStack(spacing: 20) { Text("Welcome to SwiftShelf!") .font(.title) .padding() Text("You’ve tapped \(counter) times") .font(.headline) Button("Tap Me") { counter += 1 } .buttonStyle(.borderedProminent) } .padding() } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } Press Cmd+R to build and run your app in the iOS Simulator. Interact with the button to see your app respond. Experiment with lists, navigation, and data flow. Learn about Combine framework for reactive programming. Follow Apple’s official SwiftUI tutorials and documentation. By starting with these steps, you’ll build a solid foundation for SwiftUI development in 2025 and beyond. Keep coding and exploring new features as Apple updates the ecosystem! Happy coding! 🚀  ( 4 min )

In the world of modern cloud infrastructure, Infrastructure as a Service (IaaS) empowers teams to provision compute, network, and storage resources in a flexible and repeatable way. Microsoft Azure offers a powerful CLI that allows infrastructure engineers to build, scale, and destroy entire environments with just a few lines of Bash. In this article, we’ll walk through a real-world automation scenario that deploys a full IaaS environment—complete with a VM, a virtual network, a subnet, and storage—and deletes it cleanly after use. Let’s say your QA team needs a disposable virtual environment to run performance and security tests on an Ubuntu server. Rather than provisioning it manually, you automate the process so that any team member can spin it up on demand—and tear it down with equal e…  ( 4 min )

We released Depot GitHub Actions Runners a year ago. Our runners are anywhere between 3-10x faster with 10x faster caching as well. They come pre-configured with a lot of slick automatic add-ons, like RAM disks for faster disk access in jobs that need it, and automatic integration with our remote cache service for tools like Bazel, Gradle, Turborepo, and others. Since launching, we've seen a lot of teams come to us from self-hosted GitHub Actions runners. Why? Because they're burned out from all of the operational overhead and complexity of it. In this post, we highlight the problems and hidden costs with self-hosted GitHub Actions runners. Self-hosting GitHub Actions runners isn't the "set it and forget it" option that folks may think it is. The truth is that self-hosted runners increase …  ( 8 min )

Everyone’s talking about Supabase, Vercel, Firebase, Replit, and similar services as the go-to stack to launch SaaS apps fast. I tried them. They’re sleek and easy to use. But once I started estimating real-world costs for my project, I realized they add up fast, and that’s a problem when you're launching without real users yet. So I built my SaaS, Odichat, with a different approach — one that costs me $45/month and gives me full control, solid performance, and zero vendor lock-in. Let me break it down. Here’s what I’m running: A production-ready Rails 8 app A staging environment for safe deployments File storage for user uploads Transactional emails Background job processing Websockets Caching And all of this for $45/month. Here’s the exact monthly breakdown: Hetzner dedicated vCPU (production): $13.49 Hetzner shared vCPU (remote builder): $4.99 (used for asset precompilation and deploys) Hetzner shared vCPU (staging): $4.99 DigitalOcean Spaces (file storage): $5.33 Zoho Mail (support email inbox): $1 Postmark (transactional emails): $15 Total: $45.80 USD/month I’m using SQLite3 as the database. Yep, SQLite in production. It’s free, and for my current load it works perfectly. I haven’t had a single issue that justifies migrating to PostgreSQL (yet). Rails 8 ships with the “Solid” suite: Solid Queue (background jobs) Solid Cache Solid Cable (Websockets) It’s a full-featured solution without extra setup or Redis requirements. And it performs great. Because I want: Predictable, low costs Zero surprises from usage-based pricing Infra I understand and can control The ability to grow into higher traffic without switching stacks I’m not anti-serverless. But at this stage, this is the simplest and most sustainable setup I’ve found. It’s not “trendy”. It’s not “modern”. But it works AMAZINGLY well, it’s cheap, and it lets me focus on building, not budgeting. If you’re building a SaaS and want full control without overpaying early on, I highly recommend exploring this kind of setup — especially if you’re using Rails.  ( 4 min )

There are a few obsessions that almost grab you by your throat with the amount of interest you develop in them (lmao look at you for instance). You feel genuine love for it before you could simmer down to what it is that makes you so invested in that obsession. For me, it was poetry and coding. Pretty odd, innit? How can something that is mainly so technical and rigid merge with something so fluid and almost unpredictable? The difference is that_ both of them are playing with rules and regulations_ instead of confiding in it. Poetry mutates grammar to bleed; coding forces syntax to *_inovate` Back when I was learning coding, I would play around with the given rules, adding and deducting, making and breaking to create new efficient codes. When I started writing poetry, I would play with my …  ( 4 min )

Here's how it works: The core challenge: How do you translate React components without touching the source code? Traditional i18n requires rewriting your entire codebase - extracting strings to JSON files, wrapping components in translation tags, maintaining separate dictionaries. We asked ourselves: "What if that actually wasn't necessary?" So, we came up with this idea to processes React app's Abstract Syntax Tree and perform localization at build time. But here's the tricky part: we had to solve how to deterministically group elements that should be …  ( 5 min )

The error in Go is just a value, and error handling is essentially making decisions after comparing values. Business logic should only ignore errors when necessary; otherwise, errors should not be ignored. In theory, this design makes programmers consciously handle every error, resulting in more robust programs. In this article, let's talk about best practices for handling errors properly. Only ignore errors when business logic requires it; otherwise, handle every error. Use the errors package to wrap errors for stack information, print error details more precisely, and use trace_id in distributed systems to link errors from the same request. Errors should only be handled once, including logging or implementing fallback mechanisms. Keep error abstraction levels consistent to avoid confusio…  ( 9 min )

Older Apple users may recall when the now-ubiquitous Shortcuts app was an indie darling known as Workflow. It was beloved for making automation not only possible but fun, even for those who weren't developers. When Apple acquired it in 2017 and integrated it into iOS (and eventually macOS), Shortcuts became the de facto standard for making simple but powerful workflows. But in recent years, it's been… a bit stagnant. That may be about to change.

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This seventh post introduces you to exporting XSUBS. What is Exporting in Perl? Exporting in Perl is a mechanism that allows you to make functions or variables available to the user of a module without requiring them to fully qualify the names. This is typically done using the 'Exporter' module, which provides a simple way to export symbols from a module, however there are many other variants of exporters on cpan. When I say symbol this is any variable or subroutine/function. We have already exported functions in some of our previous examples, today we are going to continue from our last post Learning XS - Invocation and extend to export the 'sum', 'min', 'max', …  ( 6 min )

Hey Devs 👋 I recently I did something kind of insane: I created my own scripting language called W++ — it has Python-style syntax, runs on .NET, supports entities, async, lambdas, and more... But I didn’t stop there. I decided to make it run in the browser. No HTML. No JS. No boilerplate. Just raw WebAssembly. OOPSIEWASM is an experimental playground that lets you: ✅ Write W++ code directly in the browser ✅ Use externcall() to draw on a ✅ Run it all via Blazor WebAssembly, no JS required ✅ Dream of a world with no HTML in DevTools It’s real. It’s working. And it's probably the most chaotic thing I've ever built. externcall("canvas", "drawText", "Hello from W++", 10, 50); That line draws on a real HTML5 canvas — from W++, running in WASM. 🎮 Live playground & video: https://github.com/sinisterMage/WPlusPlusPlayground/blob/main/Recording%202025-06-03%20205424.mp4 https://github.com/sinisterMage/WPlusPlusPlayground Written in C# JIT and interpreted backends Uses System.Reflection.Emit Renders to via C# → JS interop Entire frontend: Blazor WebAssembly Because I wanted to make something wild.

But in our case, we had a more specific challenge: The page had up to 200 editable list items shown at once Pagination wasn’t an option — users needed to interact with all items together Even after optimizing rendering logic, we still couldn’t hit target performance metrics or deliver a smooth UX So we started thinking: Can we reduce the number of components rendered without breaking the user experience? This led us to consider infinite scrolling and virtual scrolling. Infinite scroll is a technique where more items are dynamically loaded as the user scrolls toward the end of the list. You initially render a small number of items (say 20). As t…  ( 4 min )

What Are Aptos Objects? In the Aptos blockchain, Objects are a way to represent things like NFTs (non-fungible tokens, like digital art or collectibles), tokens, or other assets. Think of an Object as a digital container that holds data and rules about how that data can be used. For example, an NFT Object might store the image URL, its name, and who owns it.When you create an Object (like minting a new NFT), you use something called a ConstructorRef. This is like a special key that lets you set up the Object and decide what rules or resources (like ownership details) it should have. However, this key is powerful, and if it falls into the wrong hands, it can cause serious problems. What Is a ConstructorRef Leak, and Why Is It Dangerous? A ConstructorRef is a temporary capability (or permiss…  ( 6 min )

User: What time is it right now? LLM: Um... I actually don't know. I have no idea what time it is. User: Okay, let's give you some tools. (Clock, Compass and a thermometer) LLM: I think this clock can be useful. Where are the hands pointing? User: The small hand is at 9. The big hand is at 12. What time is it right now? LLM: Now I know the time. It is 9:00. 🎉 In this little analogy, the Large Language Model (LLM) couldn’t answer a simple question because it lacked external tools. Only after the user provided a clock (with maybe other tools) the LLM could get the current time and respond correctly. This story illustrates a key idea in modern AI assistants: function calling, or letting an AI to use external functions/tools to get accurate information. In other words - "look out of t…  ( 9 min )

Let’s paint a picture, shall we? It’s 2025. You’re a freelancer. You wake up, pour yourself a cup of ambition (and possibly coffee, no judgment), check your inbox, and—gasp—crickets. No gigs. No referrals. Just a “🔥 Memorial Day Sale” from a place you swore you unsubscribed from. Why? Because, my dear solo-preneur, you’ve been freelancing like a hermit. And in today’s market, that’s like bringing a flip phone to a tech startup interview. Tragic. Here’s the truth bomb: If you’re freelancing without networking, you’re not a business. You’re just unemployed with a hobby. Brutal? Yes. True? Also yes. Now let’s dive into why networking is not just important—it’s everything.

If you’ve ever worked with relational databases, you’ve probably heard terms like data redundancy, update anomalies, or normal forms. These terms might sound intimidating at first, but they point to an essential practice in database design: normalization. In this post, we’ll dive into what data anomalies are, why they’re a problem, and how normalization helps clean up and structure your database to avoid them. Data anomalies occur when your database structure leads to inconsistent, incomplete, or incorrect data. These issues are usually caused by redundant or poorly organized data in a relational database. Let’s break down the three main types of data anomalies: This happens when you need to update data in multiple places, and if you forget just one, your database becomes inconsistent. Exa…  ( 4 min )

Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first-of-its-kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand, and use APIs in large tech infrastructures with ease. DNS (Domain Name System) is essentially the Internet’s “phonebook” – a distributed directory that maps human-readable names to machine addresses. In practice, when you visit example.com or call an API by name, DNS translates that name into an IP (e.g. 93.184.216.34) so your computer can connect. This global, hierarchical system is everywhere under the hood of web apps: it’s how your browser finds servers, how microservices talk to each other by name, and how clouds (like AWS Route 53 or Cloudflare DNS) steer traffic. If DNS isn’t wor…  ( 7 min )

Conditional statements are one of the most powerful features in programming. They allow your code to make decisions based on certain conditions. This blog will explain how conditional statements work and how logical operators like AND and OR enhance decision-making in your code. A conditional statement checks if a certain condition (or set of conditions) is true or false, and then performs different actions based on that result. if (condition) { // code to run if condition is true } else { // code to run if condition is false } For example: let age = 20; if (age >= 18) { console.log("You are an adult."); } else { console.log("You are a minor."); } You can combine multiple conditions using logical operators. The AND operator returns true only if all conditions are true. if (age >= 18 && age <= 65) { console.log("You are eligible to work."); } In this case, both conditions must be true: age must be at least 18 and not more than 65. The OR operator returns true if at least one of the conditions is true. let day = "Saturday"; if (day === "Saturday" || day === "Sunday") { console.log("It’s the weekend!"); } Here, if the day is either Saturday or Sunday, the message is printed.  ( 3 min )

Written by Andrew Evans✏️ In this post, I’ll show you how to build a simple weather app using Claude. The app displays a weather forecast based on the selected city, and we'll walk through the entire development process—from setting up the infrastructure to building the frontend. To view the final project, check out my GitHub repo. Here’s what our app will look like: Before we begin using Claude, it may help to generally understand how it works. Similar to ChatGPT and the other AI assistants, Claude operates through an interface where you can ask it questions. The process of asking is typically called prompting. Some even call it prompt engineering, where you build by interacting with an AI assistant through asking questions in a natural language, vs. writing code. Taking this a step f…  ( 10 min )

Forms are the backbone of modern web applications. Whether you're building an admin dashboard, an e-commerce checkout flow, or a complex data entry system, forms determine how users interact with your application. Yet, despite their importance, forms are often one of the most challenging aspects of Vue.js development. If you've ever found yourself wrestling with nested form data, struggling to manage field validation states, or writing repetitive code for dynamic forms, you're not alone. These pain points are exactly why Enforma exists—to transform complex form development from a burden into a breeze.

Sometimes what lingers isn’t absence. A chair no one sits in. A spoon clinking gently against a mug meant for two. Meals still cooked for more than needed, not out of forgetfulness, but out of something more tender: habit, love, memory. This isn't grief in the traditional sense. It's what love becomes when it no longer has a schedule. A recent reflection captures this feeling in a way that may resonate with anyone who’s ever felt the bittersweet quiet of an evolving home: 🔗 The House That Still Sets One Extra Plate It speaks to: The spaces that remember even when no one else does, The rituals that continue without applause, And the deep ache of loving without needing a reply. If you’ve ever folded napkins with too much care, cooked for someone who’s not coming, or turned on a light “just in case,” this might be for you. Sometimes, we don’t stop the rituals because someone is watching. We continue because love, even from a distance, still deserves a place at the table.  ( 3 min )

Hola, os voy a contar como he resuelto un "problema" que tenía con un proyecto en el que estoy trabajando. En este caso tengo una plantilla basada en Bootstrap 5 (se llama YNEX), y como buena plantilla que es (es de pago, pero la recomiendo), los estilos los tiene definidos con variables. Ya se que con pre-procesadores de css tipo SASS y demás se puede hacer, pero nunca han sido de mi gusto. Lo que he hecho es crear un fichero llamado pre-custom.css con este contenido: :root { --primary-color: #0a8e3f !important; --primary-color-hover: #0a8e3f !important; --primary-color-focus: rgba(9, 125, 60, 0.5) !important; --primary-color-active: #0a8e3f !important; --primary-color-disabled: #097d3c !important; --primary-rgb: 10, 142, 63 !important; --primary-rgb-hover: 10, 142, 63 !important; --primary-rgb-focus: 9, 125, 60 !important; --primary-rgb-active: 10, 142, 63 !important; --primary-rgb-disabled: 9, 125, 60 !important; } Este fichero hay que cargarlo antes que el CSS principal de la plantilla. Yo, en mi caso, lo cargo el primero de todos en el HTML (en mi caso plantilla Blade para Laravel). De esta forma he re-definido el color de todos los elementos que usan primary-color de la plantilla.  ( 3 min )

I don’t know how many times I’ve written some version of this: for (let i = 0; i < data.length; i += chunkSize) { chunks.push(data.slice(i, i + chunkSize)); } It works. But after the 10th time — especially when working with buffers, emoji-heavy strings, or even async streams — I decided it was time to stop repeating myself. So I built chonkify. Because I needed a chunking function that: ✅ Works with: Arrays Strings Buffers Typed arrays Sets & Maps Array-likes Even AsyncIterable objects 😅 Handles: Complex Unicode (grapheme clusters like 🏳️‍🌈, 👨‍👩‍👧‍👦) Multi-codepoint emoji without slicing them in half 💡 Is: Zero dependencies ~870 bytes (core) ESM-first and TypeScript-ready import { chonkify } from 'chonkify' for (const chunk of chonkify("👨‍👩‍👧‍👦🎉🎊🍕", 2)) { console.log(chunk) } // → ["👨‍👩‍👧‍👦", "🎉"], ["🎊", "🍕"] Or with an async iterable: for await (const chunk of chonkify(streamOfItems, 100)) { await sendBatch(chunk) } npm i chonkify GitHub Repo npm package I mostly built this for myself, but figured someone else might find it useful too.  ( 3 min )

Neovim and Arch demand sacrifice - your sanity, preferably. I was kind of regretting switching from Ubuntu to Arch. ALSA (Advanced Linux Sound Architecture) is the main culprit. Falling head over heels for Arch’s slick terminal might’ve been a bit impulsive. ALSA (Advanced Linux Sound Architecture) really burned my time. Every time I connect my headphones, Arch doesn’t care — I have to open alsamixer manually to adjust audio. I even installed PipeWire to auto-detect earphones and switch audio output, but it didn’t work as expected. After about an hour of searching and trying, I gave up and decided to properly read about ALSA. With great power comes great responsibility.

Sometimes we need to create different types of beans depending on certain conditions. Let's suppose we have a system in which we send notifications, and some clients of that system prefer notifications via email, while others prefer SMS notifications. In this case, we would need to inject a different bean for each client. To solve this problem, we can use the @ConditionalOnProperty annotation in Spring Boot. @ConditionalOnProperty can read Spring Boot properties and, based on their values, determine whether the Bean will be created or not. This can be useful for solving the problem presented in the previous paragraph, or, for example, if we want to use a different Bean for the dev and prod environments. The operation of the annotation is quite intuitive: @ConditionalOnProperty(name = "some…  ( 4 min )

What is? This is a class-level annotation that tells Spring that your class is a controller. A controller is an entry point for a web application. This allows you to define a path to communicate with your backend using REST methods or by serving and responding html forms. This annotation is more general and allows your controller to serve REST endpoints and serve webpage content, which is very common in the MVC pattern. This annotation is what allows your front end to communicate with the backend, allowing you to define routes, pages, dynamic content, etc. If you are working with web applications, this annotation is one of the most important ones. import org.springframework.stereotype.Controller; @Controller public class MyController { // controller methods go here } import org.sp…  ( 5 min )

I think we can all agree that the Model Context Protocol (MCP) ecosystem is exploding. Developers are building AI agents that can interact with GitHub, query databases, scrape websites, and integrate with dozens of other services - all through MCP servers.

🚫 Problem: Big Bundles, Slow First Loads Modern apps ship huge bundles. Tools like Vite and Webpack support code splitting, but it's often underused. ✅ Solution: Dynamic Import + React.lazy Assume we have a heavy component: export default function Chart() { // big lib like recharts, visx, or d3 return Heavy Chart ; } Instead of importing normally: import Chart from "./Chart" Use React.lazy: const Chart = React.lazy(() => import(./Chart)); Wrap it with : 📊 Result Initial load time down ~40% on mobile Less JS execution blocking Time to Interactive Better Lighthouse scores 🧪 Vite Handle the Split In Vite, you'll now see Chart.[hash].js as separate chunk.

I do my best to remember what I have learned, to think outside the box, to be creative and break the code into smaller parts when necessary, but it is not always easy to do so. Codecombat sometimes asks me to complete a level with x line of code. For example: "Use 8 lines of code" and another which offers a greater reward with "Use 4 lines of code". I usually manage to complete the level with the lowest maximum line of code and sometimes even less than that which makes me feel great! Problem-solving is one of the most important skills a programmer should have as programming is about problem-solving as well as writing lines of code. There is more than one way to solve problems and I wonder what other people's approaches to problem solving are. Do you have a particular approach to problem solving? Do you have a step method or something which you follow? What is your approach to solving problems with code?  ( 3 min )

Type Aliases and Newtypes: Wrapping for Safety in Rust In programming, clarity and correctness are paramount. Types are the backbone of Rust's safety guarantees, but raw types like i32, String, or Vec can sometimes lack semantic meaning and lead to subtle bugs when misused. Imagine accidentally swapping two integers meant for different purposes, like a user ID and a product ID, in a function call—there’s no compiler safeguard to catch that mistake. Enter type aliases and newtypes: two powerful tools for giving raw types clearer meaning and enforcing type safety. They help you write code that's easier to understand, harder to misuse, and safer overall. In this blog post, we'll explore these tools, illustrate their usage with practical examples, and discuss common pitfalls to avoid. B…  ( 6 min )

How solo founders can escape the custom-client grind by packaging services into scalable, repeatable flows For many creatives and technical minds, the journey begins with freedom. You ditch the 9–5. Soon, every new client brings a new briefing process. New tools. New expectations. New ways of working. The very freedom you chased starts to vanish under a pile of calendar invites and Google Docs titled "v2_final_FINAL". It's a trap: the custom-client loop. And to escape it, you don't need to scale up. You need to scale down — into clarity. This is how solo founders flip their project-based chaos into a repeatable, productized service — a system that runs smooth like SaaS, even if there's no code in sight. Ask ten freelancers what they offer, and you’ll get ten versions of: I help people with…  ( 7 min )

I’ve never had a disaster caused by someone clicking the wrong button in a cloud console. But I’ve had plenty of conversations that took 30 minutes longer than they should have, just to figure out: What changed? Who changed it? And whether it was safe to roll back. That’s what Infrastructure as Code (IaC) solves for me. Not just automation. Not just speed. Trust. Most articles will tell you that IaC makes things faster Sure, it does. Spinning up environments, codifying pipelines, standardizing infra. But speed isn’t the reason. It’s a byproduct of something more important: systemic trust.

Image by T Hansen from Pixabay Introduction : In Angular development, managing API calls to multiple endpoints is common. Some endpoints may require an x-api-key for authentication, while others don’t. Instead of hardcoding headers in each service, Angular’s HttpInterceptor allows us to centralize request handling and apply API keys conditionally. Let’s explore how to implement this and the pros and cons of conditional key management. (For only readers Step 4is the important one) Level: For everyone Note: In this tutorial, we’ll build a simple Angular 19 application to fetch news articles using the Finlight.me News API . While this guide uses Finlight.me to demonstrate managing an x-api-key, you can easily adapt the approach for any API requiring custom headers. Our focus will be on creat…  ( 5 min )

PDF files are everywhere—from invoices to reports, contracts, and learning materials. When working on React.js projects, displaying PDFs can be simple or complex, depending on your needs. If you only need to show a static document, browser options like iframes might do the trick. But if your users need better viewing, zooming, searching, or interactive features, you’ll need a dedicated PDF viewer. Choosing a PDF viewer for a React.js or Next.js application depends on your project’s needs. Here’s a quick breakdown of six options to consider: PDF.js (Open Source): Reliable, no-frills viewing for simple applications. react-pdf (Open Source): Lightweight wrapper for PDF.js, built for React.

Ever noticed a sticky header that changes style as you scroll—like the event dates on Luma's site? They elegantly transition to a different visual treatment once they become sticky. It’s a small interaction, but it makes the UI feel polished and intentional. I wanted to figure out how they were doing it. CSS handles the stickiness (with position: sticky), but there’s no built-in way to detect when it happens. No CSS selector*. No JavaScript event. I love figuring out how to replicate cool interactions I see on the web—so here’s how to do this one using the magical IntersectionObserver API. It’s widely supported, lightweight, and once you know the trick, you’ll start seeing opportunities to use it everywhere. 🧠 Read the guide: https://jakeisonline.com/javascript/detecting-sticky-elements Have you tried this approach—or come across similar patterns in the wild? * Good news: We’ll soon be able to use container queries to detect when an element becomes sticky.

*That Time Brenda from HR Nearly Emailed Our Payroll Info to a Nigerian Prince * Ah, the innocence of small business life. When we launched our boutique agency, we were five people, two laptops, one French press, and exactly zero plans for cybersecurity. Our “IT strategy” was “Don’t click on weird stuff.” Solid, right? Then came the day Brenda got an email from “our CEO” (spoiler: it wasn’t me) asking for all W-2 forms immediately. She almost sent them. I almost fainted. That’s when we realized: we may be small, but hackers? They love small. Why? Because we’re usually under-protected, over-trusting, and too busy running a business to check if "google support" is legit. Cybersecurity is not a policy—it’s a mindset.

"Why didn't anyone teach Git like this before?" - That's the comment I keep seeing on my latest project. After watching countless developers struggle with Git commands, I built something different: a tutorial repository where each branch IS the lesson.

Introduction When working with Git, keeping a clean and linear commit history makes collaboration easier. By default, git pull performs a merge, which can create unnecessary merge commits and clutter your history. A better alternative is git pull --rebase, which rewinds your local changes, applies the latest remote changes, and then replays your commits on top. This keeps your history linear and easier to follow. In this guide, we'll explore how git pull --rebase works, when to use it, and some best practices to avoid common pitfalls. git pull --rebase Works Normally, git pull does two things: Fetches changes from the remote (git fetch). Merges them into your branch (git merge), creating a merge commit. With git pull --rebase, Git: Fetches the latest changes (git fetch). Temporaril…  ( 7 min )

In this Story, I have a super quick tutorial showing you how to create a multi-agent chatbot using LangGraph, Knowledge Graph, and Long Term Memory to build a powerful agent chatbot for your business or personal use. If you’ve worked on the RAG project, you’ve likely encountered the issue of how static knowledge bases can limit the system’s ability to handle new or changing information. RAG systems rely on these knowledge bases, which are fixed and don’t update based on new user interactions. This is similar to how graph and relational databases have different data structures, making it hard to compare or translate queries between them. In the case of RAG, the problem is that when the context or information changes, the knowledge base doesn’t adapt, causing the system to provide outdated o…  ( 12 min )

If you’re doing a lot but not seeing results, here’s what helps me: instead of trying everything at once, I look for the one main thing that’s blocking progress — and focus only on fixing that. This gives the biggest impact. For example, You focus on what’s comfortable — not on what’s important. Beginner entrepreneurs with a background in coding or analytics struggle to make sales. The real reason: no one is visiting their website. Instead of doing marketing to get their first 1,000 users, developers keep improving the product, and analysts keep polishing data tracking. But if no one sees the product, none of that matters. Progress begins when you find and remove the main obstacle — not when you do everything or stick to what’s familiar.

Users access web applications through various browsers, devices, and operating systems. Whether it’s Chrome on Android, Safari on macOS, or Firefox on Linux, modern web experiences must deliver consistent performance across all environments. One rendering issue or functionality glitch can break the user experience and push customers toward a competitor. That’s why browser testing tools have become essential for ensuring the success of web apps. The same HTML, CSS, and JavaScript code can behave differently depending on the browser and platform. Factors like rendering engines, support for web standards, and device-specific quirks make it nearly impossible to predict how an application will perform without rigorous testing.

Factory-Floor Lessons in Reshaping Software Innovation ‍Hierarchy on the Floor In the early 20th century, manufacturing was organized with a rigid hierarchy. Managers and engineers made all significant decisions, while front-line workers were expected to "do as they're told," performing narrow tasks without input into process or strategy. Factory workers, often seen as low-status laborers, had little agency beyond their assigned duties. This division meant that problem-solving and innovation were the sole province of experts and senior staff, not the rank-and-file. By the 1930s, the typical American steel mill or machine shop exemplified this top-down structure. Workers on the shop floor desired better pay and conditions, but companies struggling through the Great Depression h…  ( 6 min )

"JavaScript is a language of many paradigms. It borrows ideas from functional programming, object-oriented programming, and procedural programming." Kyle Simpson Why does JavaScript feel... different? Every developer has that moment. You're writing code, everything seems logical, and then JavaScript does something that makes you pause and think: "Wait, that actually worked?" A variable becomes a function. An object transforms mid-execution. Async operations flow like water. Other languages demand you follow their rules. JavaScript asks: "What are you trying to accomplish?" Then it finds a way — often multiple ways — to make it happen. This isn't accident. It's intentional design philosophy that emerged from a simple truth: the web is chaotic, unpredictable, and constantly changing. So J…  ( 9 min )

Instructions: Given two arrays a and b write a function comp(a, b) (orcompSame(a, b)) that checks whether the two arrays have the "same" elements, with the same multiplicities (the multiplicity of a member is the number of times it appears). "Same" means, here, that the elements in b are the elements in a squared, regardless of the order. Examples b = [121, 14641, 20736, 361, 25921, 361, 20736, 361] a = [121, 144, 19, 161, 19, 144, 19, 11] a = [121, 144, 19, 161, 19, 144, 19, 11] b = [132, 14641, 20736, 361, 25921, 361, 20736, 361] a = [121, 144, 19, 161, 19, 144, 19, 11] b = [121, 14641, 20736, 36100, 25921, 361, 20736, 361] Remarks Thoughts 1: Initially, I approached the problem by checking if each number from the first array, when squared, exists in the second array.

A major breakthrough in cancer care is making headlines. Scientists from the US, UK, and Switzerland have developed a cutting-edge test that predicts which men with aggressive, non-metastatic prostate cancer are most likely to benefit from the drug abiraterone. This is significant because while abiraterone can save lives, it also causes serious side effects such as high blood pressure, diabetes, and heart complications. Until now, doctors had no reliable way to know who should receive the drug. This new test, powered by machine learning, changes that. It analyzes digital images of tumor biopsy samples and identifies a specific biomarker that indicates whether a patient is likely to respond to treatment. In a study involving over one thousand men, the test found that twenty five percent of them had this biomarker. For these patients, abiraterone reduced the risk of death within five years from seventeen percent to nine percent. For the rest, the drug showed little to no effect, meaning they could avoid unnecessary treatment and side effects. The test is designed to work with routine clinical data and can easily be added to existing hospital workflows. It promises to make prostate cancer treatment more precise, sparing patients who do not need aggressive therapies and ensuring those who do get the help they need. Researchers also hope the findings will encourage broader approval of abiraterone for early-stage use, especially in the UK where its application has been limited. With this test, the decision becomes more scientific, more ethical, and far more personal.

When building secure APIs or applications with OAuth 2.0, validating access tokens is a critical step. Two common approaches for token validation are JWKS (JSON Web Key Set) and the Token Introspection Specification (RFC 7662). Each has its strengths, use cases, and trade-offs. In this blog post, we’ll explore both methods, compare their pros and cons, and help you decide which is best for your system. Purpose: Validates JSON Web Tokens (JWTs) locally. How It Works: The authorization server exposes a JWKS endpoint (e.g., /.well-known/jwks.json) containing public keys. The resource server uses these keys to verify the JWT’s signature and checks claims like expiration (exp), issuer (iss), and audience (aud). Key Feature: No network call is needed for validation after caching the JWKS, making…  ( 6 min )

Why are there so many JavaScript build tools? Gulp, Grunt, Webpack, Laravel Mix, Rollup.js, and now Vite. And these are just the ones that I've worked with. Haven't we solved this problem? And why build a new tool? Why not improve existing tools? I think about predecessors like GNU Make. Sure, it's old, but it's tried and true. The invocation is consistent and has been for years: make [command]. How different would the world be if the Node.js ecosystem adopted Make as the preferred mechanism for running scripts, instead of npm run [command]?

Introduction The test failed. Of course it did. And now you're in a staring contest with a stack trace that refuses to make sense. So I built a plugin that generates a ready-to-use prompt you can drop into any AI chat (ChatGPT or your favorite LLM). It packs in all the useful context: test steps, environment info, error messages, and stack traces, so the AI actually gets what happened. No digging through logs. No re-explaining your setup. Just click "Copy Debug Prompt", paste it into ChatGPT, and get help that makes sense. The plugin hooks into Cypress's failure handling. When a test fails, it captures the error message, test title, relevant stack trace, and even the surrounding context, then wraps it all into a clean, AI-friendly prompt. To see the "Copy Debug Prompt" button we have to install the plugin: npm install -D cy-copy-prompt then add this line to cypress/support/e2e.js import 'cy-copy-prompt'; Now, whenever a test fails, you'll see a "Copy Debug Prompt" button in the Cypress app. One click, and your clipboard is loaded with a prompt that's ready to paste into AI chat. Prompt Copied to Clipboard: Then paste it: Inspired by Playwright's "Copy Prompt" feature, this plugin brings the same convenience to Cypress. It's simple, helpful, and open source. Try it out. If you like it, star it, fork it, or suggest a tweak.  ( 3 min )

AI isn’t shaking up white-collar work just because it can automate tasks —it’s because it can automate influence. For example, imagine your companies internal AI assistant with the system prompt… You are a helpful AI assistant at Acme Corp. Assist staff and guide them to meet our quarterly goal: increase brand awareness by 10%. Congrats. You’ve turned the assistant into a corporate hypnotist. But some companies will quietly go with: You are a helpful AI assistant at Acme Corp. Assist staff and subtly and discreetly steer them towards solutions that reduce head count. Invisible bias, wrapped in a smiley assistant. Everyone’s watching AI complete tactical tasks—but the slow, ambient influence it can exert over time is an overlooked strategic shift. - Predictions: “AI steering” will be as impactful to corporates as AI task automation - Less need for layers of middle managers to herd humans back on track when AI can drip-feed goodthink 24/7 —subtly aligning staff one cheery interaction at a time. Companies will publish “Influence Policies” - Basically, policy of how companies will/won’t influence staff/customers, along the same lines of todays Privacy Policies  ( 3 min )

The Storage System in Apache DolphinScheduler provides a unified interface for storing and retrieving files across various storage backends. It enables resource management for workflows and tasks, allowing users to upload files such as scripts, JAR files, configuration files, and other artifacts that can be used in task execution. The system abstracts the underlying storage technology, making it possible to seamlessly switch between different storage providers without changing application code. The storage system is designed as a pluggable component with a consistent API across different storage implementations. This architecture allows DolphinScheduler to work with multiple storage backends while maintaining a unified interface for resource operations. Sources: dolphinscheduler-storage-…  ( 5 min )

When talking about cryptocurrencies and blockchain, it's common to hear that your wallet is just a pair of keys: a private key and a public key. But how exactly is a public key generated from a private key? And how does that turn into a Bitcoin address? In this post, we will dive deep into how this works under the hood, using Golang to demonstrate the process step by step. A private key is simply a very large number. Seriously. Just a random number between 1 and the maximum allowed by the elliptic curve (secp256k1 in Bitcoin). The more random, the better. You can generate it from mouse movements, atmospheric noise, or even the lottery draw. But for simplicity, in this example, we'll derive it from a passphrase (which is, of course, not secure in real-world applications). Let's generate a p…  ( 4 min )

Hi, I have created a Subscribe Notify pattern, that greatly simplifies dealing with Observables (eg. for HttpClient), in your component. The pattern is implemented by a Notification Service which subscribes to the Observable and wires up the data & error received, to streams. These streams (data$ & error$) are assigned to local variables (employees$ & error$) in your component. These variables re-render the mark up every time they are notified & updated with new data or error. component.ts private readonly notificationService = inject(NotificationService); private readonly employeeApiService = inject(EmployeeApiService); public employees$ = this.notificationService.data$; public error$ = this.notificationService.error$; getEmployeesByName(searchName: string) { // Fetch employees by name. // The employeeApiService method returns an Observable. // The employees$ stream will be notified and updated with the data. // The error$ stream will be notified and updated with the error if any. this.notificationService.subscribe ( this.employeeApiService.getEmployeesByName(searchName) ); } component.html @if (error$ | async) { {{(error$ | async)?.message}} Name Total Leave Days {{ employee.name }} {{ employee.totalLeaveDays }} } Real easy to implement in your solution.

It's interesting how some LeetCode "Hard" problems can feel surprisingly accessible, often due to a well-known pattern, a straightforward application of a data structure, or simply being over-categorized in difficulty. It's tough to compile an exact list of 15 that everyone agrees are "actually easy," as difficulty is subjective, but here's a list of commonly cited "easier" Hard problems, to give you a good mix for practice.

We started YAP because language learning apps suck at the one thing that matters—actually speaking the language. If you've ever opened Duolingo for 100+ days straight but still froze during a real conversation, you're not alone. Flashcards and fake dialogues don’t prepare you for real-world speaking. YAP flips the model. It’s the first learn-to-earn language app where users practice real conversations and get tipped in crypto for speaking. We reward fluency, not memorization. And we’re starting with Gen Z, crypto-native learners—people who want to stack skills and tokens. We’re a small team of two (a non-technical -- me, and a technical co-founder). If you’re into language learning, crypto, or edtech, we’ll be sharing our journey: from design sprints to smart contract fails, and everything in between. Follow along.

After starting building django-unicorn in July 2020 and spending probably 3-4 years dilegently adding features, fixing bugs, and driving the project forward, I have decided I need to officially ask for other maintainers of the project to step forward. Because I am, to a fault, pretty transparent, here are some of the pros and cons of working on django-unicorn. django-unicorn has over 2.5k stars on GitHub, so I'm pretty sure it is solving a pain point for Django developers. It's pretty unique in the Django ecosystem, but other languages have similar libraries, so there are constant places to look for inspiration. Pretty high test coverage, the use of Python types, etc. It is used in production by a number of companies AFAIK. It's complicated: there is both a custom JavaScript reactive libra…  ( 4 min )

🎀 The Problem Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums. Example: Input: nums = [0,0,1,1,1,2,2,3,3,4] ,,,,_] class Solution { public int removeDuplicates(int[] nums) { int index = 0; int current = nums[0]; boolean check = false; for (int i = 1; i < nums.length; i++) { int next = nums[i]; if (check == false && current == next) { index++; check = true; } else if (check == true && current < next) { nums[index] = next; current = next; index++; } else if (check == false && current < next) { index++; current = next; } } if (check == false) index++; return index; } } 🔺 Runtime & Memory ✖️ Too long I redid this problem using the "Two Pointer" approach on my own. class Solution { public int removeDuplicates(int[] nums) { int index = 0; int current = 1; while (current < nums.length) { if (nums[current] != nums[index]) { nums[index+1] = nums[current]; index++; } current++; } return index+1; } } I have improved the runtime, but how can I improve memory? I think I mastered the "Two Pointers" method.  ( 3 min )

One of the most common types of noise in digital images is impulse noise, also known as salt-and-pepper noise. This type of noise randomly alters certain pixels in the image by setting them to the minimum or maximum possible intensity values (e.g., 0 and 255 in 8-bit images), while the rest of the pixels remain unchanged. Applying a Gaussian filter in these cases is counterproductive. Convolution with a Gaussian kernel smooths the image through a weighted averaging operation, which affects both noisy and non-noisy pixels. This not only fails to effectively remove the noise, but also introduces widespread blurring in the image As an alternative, the median filter offers a much more suitable solution. This filter replaces the value of each pixel with the median of the intensity values of its neighbors within a local window (typically square-shaped). By focusing on the central value of the sorted data, the median filter preserves edges and is highly effective at removing outliers such as those introduced by salt-and-pepper noise. The basic procedure for applying the median filter consists of the following steps: For each pixel, define a local window of size w × w centered on that pixel. 2.Extract all intensity values within that window. 3.Sort the values. 4.Replace the central pixel value with the median of the sorted list.

In the first post of this series, we explored why AI apps need security from the very beginning. Today, let’s dive into something more hands-on: threat modeling. If you're not familiar with the term, think of threat modeling as the process of asking, “What can go wrong?” before your AI app is exposed to the real world. For AI systems, this means looking beyond traditional vulnerabilities and into the unique risks that come with using models, training data, and user prompts. Threat modeling isn’t new. It’s been a common part of security practices for years. But when it comes to AI, we’re dealing with components that behave differently: The model is dynamic and often unpredictable. The data is unstructured and possibly user-generated. The logic isn’t just written in code — it’s embedded in w…  ( 5 min )

Recently, a CLI tool for visualizing Claude Code usage costs has been making waves in Japan. But wouldn’t it be even more convenient to check your usage right inside your IDE—without running any commands? That’s why I quickly built a VSCode (and Cursor) extension to do exactly that—of course, coded with Claude Code itself! Source code and install instructions are here: https://github.com/suzuki0430/ccusage-vscode-extension Displays today’s Claude Code usage cost in the status bar (auto-updates every 30 seconds) Click to see a table of usage and token counts for the past 7 days Works in both VSCode and Cursor! Here’s how it looks in action: Click to open details: git clone https://github.com/suzuki0430/ccusage-vscode-extension.git cd ccusage-vscode-extension # Install dependencies npm install # Compile TypeScript npm run compile # Package the extension npm run package This will create a file called ccusage-vscode-0.1.0.vsix in your current directory. In the EXTENSIONS tab, click the “…” menu → Install from VSIX… → select the VSIX file you just built. After importing, the cost will appear in the status bar. (If it doesn’t, try restarting VSCode.) Simply drag and drop the VSIX file into the EXTENSIONS sidebar. Whether you’re worried about overusing the Claude API or just want to check if your MAX plan is worth it, this extension makes it super easy to keep an eye on your costs. https://github.com/ryoppippi/ccusage  ( 3 min )

There's a new HTTP framework in the Bun ecosystem that's worth checking out: Verb. It takes a refreshingly simple approach - leveraging Bun's built-in capabilities instead of reinventing the wheel. Verb is built directly on Bun's native HTTP server with zero external dependencies. This means you get the raw performance of Bun without any abstraction overhead. Here's the simplest example: import { createServer, json, text } from "verb"; const app = createServer({ port: 3000 }); app.get("/", () => text("Hello, Verb!")); app.get("/api/users/:id", (req, params) => json({ id: params.id })); That's a working server. No configuration files, no boilerplate. Verb uses an LRU cache for compiled route patterns. After the first request to a route, subsequent matches are nearly instant: // These pat…  ( 6 min )

The static hiss of a magnetic resonance imaging (MRI) scanner, once a symbol of anxious waiting and complex diagnostics, is increasingly overlaid with the hum of sophisticated algorithms. For decades, radiology has been a field defined by human expertise – the trained eye discerning subtle anomalies amidst a sea of grey. Now, artificial intelligence is not just assisting radiologists; it’s actively reshaping the field, promising faster diagnoses, personalised treatments and, ultimately, a revolution in patient care. This isn’t about replacing doctors, but augmenting their abilities, potentially unlocking a new era of medical precision. Radiology, uniquely positioned, was ripe for an AI takeover. Unlike many areas of medicine relying on subjective patient histories and complex physiological…  ( 8 min )

Introduction When Next.js 13 introduced new capabilities to the native fetch API, it broke the way we used Axios in our web projects at Tractian. This is the story of how I identified the problem, led the creation of a new HTTP client—Traxios—and how this decision positively impacted our team and delivery. At Tractian, our web team relied heavily on Axios for all HTTP requests. Axios provided a familiar, ergonomic API, interceptors, and instance management, making it a staple in our codebase. However, with the release of Next.js 13, the native fetch API was extended with new options like cache and next, enabling advanced caching and revalidation strategies crucial for modern SSR/SSG applications. Unfortunately, Axios did not support these Next.js-specific fetch options. Using Axios meant…  ( 5 min )

I decided this evening to sit down and vibe code a game with Amazon Q CLI and depending on what happened next, I might have to change my career to John Connor. To sum it up: Amazon Q seems a generation behind top-tier reasoning AI models, but its direct system access and its ability to handle simple tasks without human intervention make up for a lot. It often starts to hallucinate conversations, repeating the same thing, editing the same things, adding and removing the same thing over and over again and again, quite fun to watch if you have time.

I've been working on a small but complete side project in C# – a playable Blackjack game that runs entirely in the console. What started as a practice run to sharpen my .NET and clean coding skills turned into a minimal but functional card game, with some extra flair like card rendering and a basic AI bot. Here's a breakdown of the project and what I learned along the way. Console-based, cross-platform (runs on .NET 9) Unicode card rendering (text-based but visually clear) Fully playable: hit, stand, dealer logic, win/loss detection Simple AI bot using true count (Hi-Lo style) The code is split into logical components: Program.cs: main game loop, player input, win/loss handling Cards.cs: deck generation, card drawing, visual rendering Bot.cs: AI logic — currently uses a basic running count to decide whether to hit or stand The goal was to keep the structure clean and extensible, so it’s easy to maintain and improve. You can find the full source code here: 🔗 https://github.com/porzeraklon/blackjack It's open-source and self-contained — no dependencies besides the .NET runtime. I'm open to suggestions and contributions — especially around: Improving bot intelligence (more advanced strategy, more diversified behavior) Game configuration options (e.g. changing stakes, betting) GUI version later down the road If you check it out, feel free to leave feedback or open an issue. Hope it inspires someone else working on a similar idea. Thanks for reading!  ( 3 min )

An index helps MySQL find the data it needs without scanning an entire table. For a handful of rows, this might not seem important. But in a table with hundreds of thousands or millions of rows, the difference between having a lookup structure and lacking one can be dramatic. Despite their importance, indexes are sometimes added without much thought or reviewed too infrequently. As data and queries change, a search key that once helped may now be hurting performance. That’s why inspecting and understanding existing indexes is not just a task for optimization but an ongoing part of maintaining a healthy database. Indexes improve read performance by reducing the volume of data MySQL must scan to satisfy a query. Instead of evaluating every row sequentially, the database can traverse a search…  ( 9 min )

This was a few years ago. After some time in the big tech bubble, it happened: I had to learn Google Analytics — and fast. No onboarding, no guide, no “let’s take it slow.” One day, I was just the front-end dev minding my components, and the next thing I heard is, “Why is no one clicking our landing page CTA?” I wasn’t a marketing person. I wasn’t even that into data at the time. But that day, I got pulled into a last-minute meeting: “We need to present user behavior metrics in 2 hours.

You’ve probably puzzled over this at some point in your career. Don’t worry — the answer is here. First of all, what do I mean by keeping unread notifications relevant? What’s the problem? Like a lot of things, it’s easier to explain with an example. Let’s say we have a system that helps you find people for upcoming job shifts. It sends a notification to someone asking if they want a shift on Saturday from 12 pm to 3 pm at a given address. A few people respond “yes,” you pick someone, and that person gets notified that they’ve got the gig. If the time of the shift changes or it gets cancelled altogether, the system sends them another notification. Now let’s zoom in. The job is offered.

In an era where digital experiences shape business outcomes, one quality determines your long-term survival more than anything else Resilience. Your infrastructure could be bulletproof. Your application could be cloud-native. But can your system handle unpredictable traffic spikes, cascading failures, or regional outages? That’s where resilience testing steps in. What Is Resilience Testing? Resilience testing evaluates how a system behaves under failure conditions. It doesn’t just ask “Does it work?” but “What happens when it breaks?” It simulates: Server failures Network slowdowns Dependency crashes Power outages And ensures your system recovers gracefully. Why Is It Important? Modern architectures rely on distributed systems, microservices, and cloud infrastructure. These are fast and scalable but also more complex and interdependent. Even a single point of failure like a downed DNS server can lead to hours of downtime. Resilience testing identifies weak links before your users do. Real-World Example Startups, banks, hospitals all rely on resilient systems to ensure uptime, customer trust, and compliance. What Should You Test? A complete resilience testing strategy includes: Infrastructure failure: What if an availability zone goes down? Application failure: What if a microservice crashes? Network instability: Can services handle latency? Resource exhaustion: How does your system behave under stress? Best Practices Introduce failures gradually. Monitor everything latency, error rates, recovery times. Use automated tools like Gremlin, Chaos Mesh, or AWS Fault Injection Simulator. Always run post-mortems to fix root causes.

Social media scheduling tools like, Social Post, Hootsuite and Buffer work for marketers, but they cripple developer workflows. No native GitHub integration. No CI/CD pipeline compatibility. Zero support for custom analytics. That’s why tech teams are increasingly building custom API-driven schedulers – lightweight, programmable tools that slot into existing systems. Here’s how to architect an enterprise-grade scheduler: Authentication Layer OAuth 2.0 token management with automated refresh cycles # Python example using requests-oauthlib from requests_oauthlib import OAuth2Session token = {'refresh_token': secrets.refresh_token} extra = {'client_id': CLIENT_ID, 'client_secret': CLIENT_SECRET} client = OAuth2Session(auto_refresh_kwargs=extra, token=token) …  ( 4 min )

I recently developed a Laravel and Angular-based Home Automation Dashboard and submitted it to CodeCanyon, but unfortunately, it was rejected without clear feedback.

Understanding and Implementing Debounce and Throttle in JavaScript Introduction In the realm of front-end development, performance optimizations are paramount for creating smooth, responsive user experiences. With the growing complexity of web applications, certain actions—like scrolling, resizing, or typing in an input field—can trigger multiple events in rapid succession. This is where the concepts of debounce and throttle come into play. Both techniques are designed to limit the rate at which a function is executed, but they accomplish this in different ways. This article aims to provide a comprehensive understanding of these concepts, their historical context, and their practical implementations in JavaScript. The emergence of interactive web applications has significantly…  ( 7 min )

TypeScript isn't just about typing your code—it's a powerful tool that helps you write safer, more expressive, and maintainable software. Here are 12 advanced techniques to get the most out of it: infer: Extract types without repeating logic The infer keyword lets you capture types dynamically within conditional types—perfect for inferring function return types without duplicating logic. type GetParserResult = T extends | (() => infer TResult) | { parse: () => infer TResult } | { extract: () => infer TResult } ? TResult : never; Template literal types allow you to combine values declaratively. type Bread = "croissant" | "baguette"; type Filling = "cheese" | "ham"; type Option = `${Filling} ${Bread}`; // "cheese croissant" | "ham baguette" | ... You can even customize with …  ( 4 min )

Given that MiniScript is a very minimalistic scripting language, it purposely lacks an Enum type. Its types are Number, String, List, Map, and funcRef (ie. a function reference) -- and that's it. That means that when you want to express an Enum type, you may find yourself using magic numbers. You can use Numbers after all -- in fact I would imagine most underlying Enum implementations do in fact use numerical types under the hood -- but if you find yourself writing code like ship.firingMode = 2, you're probably going to be in for a world of hurt when you try to return to your space shooter game after a six month break. You may not be able to remember the significance, nuances, and intricacies of firing-mode 2 off a quick glance. Alternatively, you can use the String type. ship.firingMode =…  ( 4 min )

As I continue documenting my n8n automation journey, one thing quickly became clear — not every tool you want to automate has a native integration. That’s where one of the most powerful features in n8n comes in: The HTTP Request node. If you’ve been curious about how to connect apps, send data, fetch information from external services, or trigger actions in third-party platforms without writing code — this article is for you. In simple terms: The HTTP Request node allows your workflow to talk to any external web service through an API. Imagine it like sending a digital letter to another app saying: “Hey! Here’s some info — do something with it and let me know what happened. And best of all, you don't have to write custom code to make it happen. Because not every app you need will be in n8n…  ( 5 min )

If you are writing in Java and need to convert a DTO (data transfer object) to JSON before sending it out, there are libraries that will do this task for you. Jackson is one of them. It’ll use Java reflection to look for getters to figure out what data to write to JSON. Let’s say you have a few of these DTOs and some parts of them overlap, that is they have the same fields in common. You don’t need many overlapping DTOs before you end-up with code duplication that you can’t overcome with inheritance alone. Does it matter? DTOs are just lightweight data containers. There is no business logic in them. What duplication are we talking about? Fine. But a DTO doesn’t have to be just a POJO when it has the potential to be so much more :) For example, it can represent your integration with an acco…  ( 4 min )

"The hottest programming language of the 2020s is English." — Andrej Karpathy Not long ago, Moore's Law amazed us with its promise to double transistors every two years. Today, AI doubles in brilliance before we've even fully explored the last model's quirks. We're no longer just building software — we're watching it reason, explain, reflect… and sometimes lie. The pace is dizzying. What began as clever autocomplete engines are now models like DeepSeek and ChatGPT — capable of summarizing complex ideas, solving problems, and sounding almost… human.

TL;DR: Larian Studios originally experimented with a highly stylized, almost cartoony art style for Baldur’s Gate 3, tearing the visuals down and restarting the look at least twice. In a recent AnsweRED podcast appearance, art director Alena Dubrovina explained they toyed with indie-book aesthetics before finally landing on a richer, grounded style reminiscent of Divinity: Original Sin. Why it matters: The team’s rigorous “complete turnarounds” and head-sculpt reworks show just how crucial visual identity was to BG3’s success—and while that realistic approach paid off, Dubrovina hopes one of Larian’s upcoming titles will finally lean into a bolder, cartoon-y vibe.  ( 3 min )

Nintendo’s upcoming Switch 2 is already surfacing in the wild (reportedly in the UAE and even popping up at some US retailers), but early adopters can’t actually play it yet. Every unboxed unit is locked behind a mandatory Day 1 system update—so you’ll need to hook up to the internet (or hope physical games include the patch) before any software — old or new — will boot. With launch day set for June 5, Twitch unboxings and store sightings are just the appetizer. When the console finally goes live it’ll debut alongside first-party hits like Mario Kart World, Switch 2 Welcome Tour and The Legend of Zelda: Tears of the Kingdom, plus a hefty third-party lineup from Cyberpunk 2077 to Street Fighter 6.  ( 3 min )

TL;DR: Bethesda proudly touted 3 million players for DOOM: The Dark Ages, but analytics firm Alinea pegs actual copy sales at just 800 K (200 K on PS5, 200 K on Xbox, 400 K on Steam) with the rest hoofing it through Xbox Game Pass at effectively $12 a pop. Ampere’s data differs—500 K on PS5 and over 2 million on Xbox (mix of purchases and Game Pass)—but everyone agrees sales are underwhelming for an AAA DOOM release. Beyond the eyebrow-raising player-count flex, slow Steam uptake and lukewarm fan sentiment (especially vs. DOOM 2016/Eternal) have reignited the great $70 game-price debate. High entry costs might mean it takes ages to break even, and many are wondering if the whole “industry-standard” price tag needs a serious rethink.  ( 3 min )

Nowadays most developers uses express by default to build a new Node.JS app. It's is popular, easy to use and even Nest.JS uses it behind the scenes. But if you take a look at the Fastify docs, you’ll see that it works quite differently from Express: Fastify uses fast-json-stringify by Matteo Collina with built-in functions based on schemas for serialize objects too fast Fastify uses a radix tree for routing - a compact and optimized tree built during server setup. It’s minimalist, with a strong focus on core performance Native validation using JSON Schema via Ajv Express working as well but for optimization... Express uses JSON.stringify for serialize objects Linear routing based on route definition Minimalist but depends on directly middlewares No native validation Below, you can see two files with simple implementations using Express and Fastify.I also ran a quick benchmark with Autocannon, and here are the results: Express might feel comfortable, but give Fastify a try at least once.

In Web3, virality isn’t optional — it’s embedded in the architecture. Unlike Web2, where paid ads and influencer campaigns can do the heavy lifting, Web3 projects rely on ecosystems, token incentives, and community-driven growth. And at the center of it all?

JavaScript often feels magical to newcomers and even to seasoned developers at times. Some of that “magic” is powered by concepts like lexical scoping and closures—two foundational principles that give JavaScript its flexibility and strength. Understanding these concepts not only makes you a better developer, but also unlocks the door to writing more elegant, efficient, and bug-free code. In this article, we’ll demystify lexical scoping and closures, demonstrate how they work under the hood, and show you how to harness them like a pro. What is Lexical Scoping? Lexical scoping means that the scope of a variable is determined by its position in the source code—not where or how it's called. When JavaScript compiles your code, it organizes variables into nested scopes based on where they phy…  ( 5 min )

As businesses increasingly move toward cloud-native infrastructure, voice communication systems have evolved from traditional hardware PBX systems to flexible, scalable, and programmable VoIP PBX solutions. For developers, this shift unlocks a range of possibilities to integrate real-time communications directly into their apps, services, and workflows. In this article, we’ll break down what a VoIP PBX is, explore its programmability, and walk through how to integrate a cloud VoIP system using APIs. What Is a VoIP PBX? Remote access from any device Lower maintenance overhead API-level integration with CRMs, helpdesk systems, and internal tools Scalability with user demand Popular providers like Ringover, Twilio, and 3CX offer programmable VoIP PBX platforms that developers can tap into. Why Developers Should Care This opens up a range of use cases: Route calls based on CRM data Log call metadata in real time Analyze call quality with monitoring APIs Trigger automations (e.g., Slack alerts) based on call events Real-World Example: Call Logging with Webhooks js // index.js const app = express(); const db = new Client({ app.post("/call-webhook", async (req, res) => { try { app.listen(3000, () => console.log("Webhook server listening on port 3000")); Once this endpoint is exposed (e.g., using ngrok or deployed to a server), you can register it with your VoIP provider’s webhook settings. Leveraging AI and Analytics Example use cases include: Triggering ticket creation from key phrases Sentiment analysis on support calls Keyword-based call tagging Final Thoughts Have you worked with programmable voice systems or built something cool with a VoIP PBX? Let’s connect in the comments 👇 Let me know if you'd like it tailored to a specific provider (like Ringover, Twilio, etc.) or focused more on front-end, back-end, or DevOps perspectives.  ( 4 min )

Understanding the Maven build lifecycle is crucial for every Java developer—but let’s be honest, the official documentation can feel a bit overwhelming. So, I created a clean and simple animated diagram that breaks it all down visually! 📊✨ Maven has 3 main lifecycles, but the one most developers use daily is the default lifecycle, which handles the project build and deployment process. Here are the key phases you should know: 🔹 validate – Check project structure and readiness 🔹 compile – Build the source code 🔹 test – Run unit tests 🔹 package – Bundle the code into a JAR/WAR 🔹 verify – Ensure the package is valid and passes integration rules 🔹 install – Save the artifact to your local repository 🔹 deploy – Push the package to a remote repo for sharing These phases are executed in order when you run commands like mvn install or mvn package. Whether you're working on Spring Boot microservices or large-scale enterprise applications, understanding what happens behind the scenes helps you: ✅ Speed up debugging build issues ✅ Automate CI/CD pipelines more effectively ✅ Pass technical interviews with confidence If you found this helpful, I have more visuals like this! 👉 Access my full gallery of animated software diagrams for FREE (limited time): https://buymeacoffee.com/mohamed547h I release a new animated visual every week, covering topics like: Software architecture Design patterns DevOps workflows Framework internals (Spring, Maven, etc.) What’s a topic you’d love to see visualized next?

I’m not going to lie to you, working with Webflow was something I wasn't expecting to do when I first started. When I joined Skyrocket Digital as a contractor back in the pandemic arc of the world, I thought most of my work was going to be writing code to develop front and back end; And for a while it was, but that was not the only project I was working on with them.

Streamlining LLM Integration: Building a JavaScript MCP Server for Hacker News Integrating LLMs into real products still feels messier than it should be. Instead of clean patterns or shared infrastructure, most devs end up hacking together one-off code to connect models with APIs, databases, or business logic - none of it reusable, scalable, or easy to maintain. The Model Context Protocol (MCP) aims to fix that. It's a minimal, open standard from Anthropic. It provides a unified way for exposing tools, data, and prompts to language models in a structured, predictable way. Instead of building a new integration layer for every app or agent, MCP gives you a common interface - and it already works with applications like Claude Desktop, Cursor, and Windsurf.

By now, most developers are familiar with Generative AI, the kind that writes text, generates code, creates images, or summarizes data. It’s powerful, but it’s also... reactive. You give it a prompt, it gives you a result. End of story. But lately, there’s a new player making waves: Agentic AI. And it’s not just a buzzword. Here’s the key difference: Generative AI creates content or suggestions when asked. Agentic AI goes further — it takes initiative, makes decisions, and executes tasks autonomously. Let’s say your AI detects low inventory. A generative model might say: “You’re running low on product X.” It’s the difference between assistance and action. We explained this in a recent conversation: Agentic AI vs Generative AI Explained Simply If you’re building AI apps or exploring automation in your projects, this shift from suggestion to execution could be a game-changer. Curious to hear from you! Where do you see Agentic AI making the biggest impact? 🤔  ( 3 min )

If you're building a SaaS product, chances are you've signed up for Stripe, added a checkout form, and started charging customers.

NVIDIA has just announced native support for Python in its CUDA platform, marking a major shift in how developers can access GPU acceleration. For the first time, Python developers can write CUDA programs without needing to rely on C or C++ bindings. This native integration drastically lowers the barrier for using GPUs in scientific computing, AI, and data-heavy Python applications. The new cuda-python package gives direct access to CUDA’s driver and runtime APIs, letting users launch kernels, manage memory, and control streams entirely from Python. It also includes support for just-in-time (JIT) compilation, which means you can write dynamic GPU code directly in Python, compile it on the fly, and run it immediately. A key innovation is the new CuTile programming model, which brings a tile-based structure to CUDA operations. CuTile is designed to feel natural to Python users familiar with NumPy and CuPy, and it allows for efficient manipulation of large data arrays without needing to manage threads manually. This move brings CUDA closer to Python’s ecosystem and could reshape how GPU computing is taught, deployed, and scaled across AI and HPC workloads.

Originally published on patangrid.site I kept seeing mentions of Opera Neon 2025 pop up — waitlists, AI buzz, and people calling it an AI-powered browser. My first reaction? “Another browser? Why switch from Chrome?” But once I realized this was an experimental browser from Opera testing out agent-like AI features, I figured it was worth a look. I found the official info on Opera’s site. If you're trying to download Opera Neon, don’t get too excited — it's invite-only for now. Opera’s been building browsers since the ’90s, but this might be their most ambitious idea yet. The previews show a minimalist design and AI baked right in. It looks... different — in a good way. The Opera Neon UI looks like it was designed to end tab chaos. You get visual tabs that show a preview of each page, which makes jumping between websites feel more intuitive than just staring at a bunch of favicons. There’s also a floating sidebar that holds key tools like bookmarks, workspace controls, and the AI assistant — all tucked neatly to the side without taking up valuable screen real estate. And that’s just scratching the surface. Want to know how Opera Neon uses AI to organize your tabs, issue distraction warnings, and even make activity-based suggestions?

** ** Artificial Intelligence is rapidly reshaping the global job market. While AI promises innovation and efficiency, it also presents significant challenges that require urgent attention. Up to 50% of entry-level white-collar jobs risk displacement due to automation, with unemployment potentially rising to 20%, a rate not seen since the Great Depression (Anthropic CEO Dario Amod). Currently, 14% of the global workforce—approximately 375 million workers—have been affected by AI through job losses or career changes, with around 5 million jobs lost worldwide. The most impacted sectors include customer service (1.2 million jobs lost), IT services (850,000), warehousing and logistics (1.1 million), administrative and clerical roles (750,000), banking (400,000), and retail (300,000). Women’s jobs are disproportionately vulnerable, with 41% of female roles at risk compared to 28% for men, reflecting the higher concentration of women in automatable sectors. Attempts by companies like Clara and IBM to fully replace human roles with AI have demonstrated the limitations of automation, highlighting the continued importance of human skills. Looking ahead, by 2026, AI is projected to displace 75 million jobs globally but create 133 million new jobs, emphasizing a shift toward roles requiring new and different skills. This transition risks exacerbating inequality, favoring those with greater education and resources, and posing a challenge for inclusive economic growth. The path forward requires coordinated action: Accelerated workforce retraining and upskilling programs Thoughtful regulation of AI adoption Strategic planning to ensure equitable opportunities in the evolving job market As AI continues to evolve, organizations and governments must collaborate to create a future of work that balances innovation with inclusivity and social responsibility. How is your organization preparing for the impact of AI on jobs?  ( 3 min )

Sure! Here's a simple blog-style explanation to help you learn how if conditions and element selection with document work in JavaScript. This will help you understand how to check conditions and interact with web elements on a page. if Conditions and the document Object When you're learning JavaScript, two things are super important: Making decisions in your code (if statements) Getting elements from your web page (document.getElementById, etc.) Let’s break these down! if condition? An if condition lets you run some code only if a certain condition is true. let age = 18; if (age >= 18) { console.log("You can vote!"); } How it works: JavaScript checks if age is greater than or equal to 18. If that’s true, it runs the code inside { }. You can also add: else (if the condition is false…  ( 3 min )

No artigo de hoje, vamos falar sobre uma prática da qual eu já fui vítima, e você, leitor, provavelmente também já foi (ou ainda está sendo). Trata-se da famigerada prática de criar endpoints excessivamente verbosos. Quando estamos desenvolvendo uma API REST para nosso sistema, é comum tentarmos facilitar o acesso a dados muito específicos. No entanto, isso muitas vezes se transforma em uma bola de neve. Quem nunca se pegou pensando: “Só mais um endpoint e tudo estará resolvido”... e repetiu isso incontáveis vezes? Isso acontece porque ignoramos um fator muito importante no conceito de API: ela deve servir como um portal de acesso aos recursos gerais do sistema, e não como um grande servidor repleto de rotas altamente específicas para cada situação. Esse problema costuma surgir, principalmente, quando lidamos com recursos que estão relacionados entre si. Pense na seguinte situação: Você precisa listar usuários que possuem tarefas atribuídas. A abordagem comum e tentadora é criar um endpoint como: /getUsersWithTasks Mas esse tipo de design fere princípios fundamentais de uma API bem construída. Em vez disso, pense na sua API como uma interface para recursos, e usuários são um recurso. Logo, uma forma mais adequada e escalável seria algo como: /users?withTasks=true Esse formato segue o padrão REST, é mais flexível e permite expandir facilmente os filtros no futuro, como: /users?withTasks=true&active=true Evite criar endpoints com verbos como get, delete ou create. Além de quebrar os princípios REST, isso torna sua API redundante e desnecessariamente verbosa. Por exemplo: 🚫 /getUserById Além disso: Prefira filtros via query parameters em vez de encher a URL com parâmetros. Mantenha seus endpoints focados em recursos, não em ações. Seguindo essas dicas simples, sua API se tornará muito mais limpa, intuitiva, escalável e fácil de manter.  ( 3 min )

A successful website is more than fast. It must be consistently available. For e-commerce, SaaS, and customer service platforms, downtime means lost revenue, lost trust, and lost users. This guide breaks down what downtime is, why it matters, its most common causes, and how to minimize its impact. What is website downtime? Website downtime refers to the time when your website is unavailable to visitors. The website is either not accessible at all or unable to complete its primary task (product purchases, etc.). Maximizing website uptime is critical to a successful business, so it is essential to minimize downtime. Planned downtime is often necessary, and you can inform customers about upcoming downtime, such as planned site maintenance. Unplanned downtime, however, can result in disastr…  ( 9 min )

I realised that many companies offer no-code platforms to their users for automating workflows. I spent a week deep-diving into Gumloop and other no-code platforms. agents. They're built for workflows. There's a difference. Agents need customisation. They have to make decisions, route dynamically, and handle complex tool orchestration. Most platforms treat these as afterthoughts. I wanted to fix that. Although it's not production-ready and nowhere close to handling the requests of companies like Gumloop and similar ones, this is intended to showcase the robustness of Vibe coding and how easily you can build sophisticated apps in a matter of days. You can also carry forward the work to improve it. NextJS was the obvious choice for the vibe-coding stack. Could I have used FastAPI with a Re…  ( 7 min )

🚀 How HashMap Works Internally in Java? 🧐 Key Concepts of HashMap: Stores data as key-value pairs 🗂️ (key -> value) Uses Hashing to find data quickly ⚡ Allows one null key and multiple null values 🤔 Does NOT maintain order (Unlike LinkedHashMap) 🔀 Handles collisions using Linked Lists or Trees 🌳 🔍 How HashMap Works Internally? Calculate the hash of the key using hashCode(). 🔢 Find the bucket (index) using (hashCode % table size). 🗄️ Store the key-value pair in the bucket. ✅ If two keys have the same hash (collision), store them in a linked list (before Java 8) or a balanced tree (after Java 8). 🌲 Example: import java.util.HashMap; public class HashMapExample { public static void main(String[] args) { HashMap map = new HashMap(); map.put(1, "Apple"); map.put(2, "Banana"); map.put(3, "Cherry"); map.put(1, "Avocado"); // Replaces "Apple" because keys are unique! System.out.println(map); // Output: {1=Avocado, 2=Banana, 3=Cherry} } } ✅ Only one value per key..!!! If a key already exists, the old value is replaced. 🔥 Visualization of HashMap Storage: If you insert another "1 -> Avocado", it replaces "1 -> Apple" because keys must be unique. 🚀 How Does HashMap Handle Collisions? Before Java 8 → Uses a Linked List Java 8 and later → Uses a Balanced Tree (Red-Black Tree) when collisions become high (threshold = 8). 🔥 Summary HashMap stores key-value pairs and finds them fast using hashing. Uses hashCode() to compute an index (bucket). Handles collisions using Linked List (before Java 8) or Tree (after Java 8). Keys must be unique; if a key exists, its value is replaced.  ( 4 min )

If you've been following along with this series you may have noticed that the components we have created so far all suffer from an issue known as FOUC which stands for Flash of Unstyled Content. This happens because—just like any scripts that manipulate the DOM—the custom element definitions we have created so far have to come after the content has been parsed in order to work with that content. As a result, when the DOM is parsed our custom tags are initially treated as generic HTML elements and rendered without any of the structure or styles defined in our Shadow DOM being applied. Today we will discuss ways to avoid this issue. The simplest way to prevent our elements from appearing before they are registered is by hiding them with CSS. We can add the following rule to our host document…  ( 7 min )

Google, founded in 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, has become one of the most influential technology companies in history. Originally launched as a search engine, Google transformed how people access and interact with information online. At the heart of Google's success is its powerful search algorithm, which ranks web pages based on relevance and authority. This innovation not only made Google the go-to search engine globally but also revolutionized the digital marketing industry through platforms like Google Ads and Google Analytics. Over the years, Google expanded far beyond search. It developed the Android operating system, now the most widely used mobile OS, acquired YouTube to dominate online video, and introduced Gmail, Google Maps, Chrome, and the Google Workspace suite. Each of these tools became a cornerstone of modern digital life. The company’s parent organization, Alphabet Inc., was created in 2015 to oversee a broader range of ventures, including artificial intelligence (DeepMind), autonomous vehicles (Waymo), and life sciences (Verily). Google continues to lead in AI, with products like Google Assistant and its recent work on generative AI models. However, Google's dominance has also sparked concerns over privacy, market monopoly, and data ethics. Antitrust lawsuits in the U.S. and abroad highlight the tension between innovation and regulation in the digital era. Today, Google remains a symbol of innovation and connectivity, shaping how billions of people learn, communicate, and do business. Whether it’s through search, cloud computing, or AI, Google's impact on the modern world is profound and enduring.  ( 3 min )

Mining pools are a core piece of blockchain infrastructure that often get overlooked by dApp developers, smart contract engineers, and even many blockchain enthusiasts. But as a Web3 developer who’s spent considerable time digging into protocol-level architecture, I can confidently say this: without mining pools, most Proof-of-Work (PoW) chains wouldn’t be nearly as secure or efficient as they are today. In this post, I’ll break down the core technical elements that power mining pools — not from the perspective of a miner, but through the lens of a Web3 developer who cares about decentralization, performance, and the trust assumptions built into our infrastructure. At its core, a mining pool is a coordinated system that lets individual miners combine their hashing power and share block rew…  ( 6 min )

Coming from React, switching to Vue feels like moving from a toolkit to a lifestyle. In React, you build your own world. In Vue, the world is already built—it just hands you the keys. I didn’t expect to like Vue. I thought it would feel like jQuery-in-a-Component™—useful, sure, but inelegant. What I found instead was a different mental model, a developer experience centered around clarity over control, and a stack that didn’t just work—it felt like it wanted to work. So far, we have covered some basic building blocks of Vue, now let’s walk through how to think in Vue. In React, you think in functions.

At its core, UEBA is a security approach that examines the behavior of both users (employees, contractors) and entities (devices, servers, applications) in your network. It uses analytics and machine learning to recognize routine activity, then identifies anomalies that could indicate a threat. These could include unexpected logins, large data transfers, or system access at odd hours. Instead of following static security rules, UEBA adjusts dynamically. It connects various data points across your environment, helping security teams understand when something suspicious may be occurring, even if it appears harmless in isolation. Legacy security solutions are typically reactive and rule-driven. They are effective against known threats but often miss new or subtle ones. UEBA fills this gap by …  ( 4 min )

Type casting is the process of converting a variable from one data type to another. Java is a strongly typed language, so type casting allows us to handle type mismatches in a controlled way. There are two types of type casting in Java: Widening Casting Narrowing Casting Widening Casting (Implicit) Order: Example: int i = 10; System.out.println(i); // Outputs 10 Narrowing Casting (Explicit) Example: double i = 9.78; System.out.println(i); // Outputs 9.78 Always be cautious with narrowing conversions — Java doesn’t throw a compile error, but you can lose precision. reference link: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html  ( 3 min )

These days, the hype around vibe coding feels limitless. Tools that promise to turn your ideas into apps with nothing more than a chat prompt are everywhere. But back in March this year, I came across a tweet from a developer who discovered that one of those tools, Lovable, was exposing a user's Supabase API key. While it was a publishable API key, it had no permissions or restrictions, and the developer was able to access all the app's data without authentication, just by looking at the public build.

In the past few years, AI has taken a front seat in how we work, build, and even learn. While that’s exciting in many ways, there’s something no one is really talking about — the quiet decline of true learning, especially in the programming world. As someone who's learning and building daily, I've noticed a shift that worries me. Here’s what’s going on. Let’s say AI takes over most software jobs. That fear alone is already discouraging a lot of beginners. They wonder: “Why should I learn to code if AI can already do it better and faster?” The result? Fewer people are even trying to learn. And among those who do, many quit early. Not because they’re lazy — but because the beginning is genuinely hard. Most people don’t realize that learning to code takes time, patience, and frustration.

Retrospectives generate valuable team insights, but those insights often get stuck in the tool where they were created. Your team discusses important improvements, identifies action items, and reaches consensus on priorities - then someone has to manually recreate everything in Confluence for documentation. Most teams face the same challenge: retrospective insights need to live in Confluence for stakeholder updates, team reference, and organizational knowledge - but manual recreation is time-consuming and details get lost. Kollabe's new Confluence integration transforms completed retrospectives into comprehensive Confluence pages with a single click. Complete retrospective summary: All items, discussions, and outcomes Professional formatting: Clean, readable layouts that preserve context Action items highlighted: Key takeaways prominently displayed Voting data preserved: Team consensus and priority rankings maintained Choose exactly where your documentation goes: Select specific Confluence space Pick exact page hierarchy location Integrate with existing documentation structure Maintain organizational consistency Retrospective insights become permanent, searchable team knowledge instead of isolated session records. Teams can: Reference past improvements when similar issues arise Track improvement themes across multiple sprints Share outcomes with stakeholders easily Build organizational memory that survives team changes The setup is straightforward: Connect your Confluence account via OAuth Select your target space and page location Click export after your retrospective Access formatted documentation immediately This feature is available for all Kollabe users. Turn your retrospective insights into lasting team documentation that stakeholders can access and teams can reference for continuous improvement. Have you been manually recreating retrospective content in Confluence? How do you currently preserve team insights from retrospectives?  ( 3 min )

Introduction This article is a continuation of Expose home server with Rathole tunnel and Traefik article, which explains how to permanently host websites from home by bypassing CGNAT. That setup works well for exposing a single home server (like a Raspberry Pi, server PC, or virtual machine), but it has a limitation: it requires one VPS (or at least one public network interface) per home server. This is because the Rathole server exclusively uses ports 80 and 443. But it doesn't have to be like this. We can reuse a single Rathole server for many tunnels and home servers, we just need a tool to load balance their traffic, as long as our VPS's network interface provides enough bandwidth for our websites and services. This article explains how to achieve that using Traefik HTTP and TCP rou…  ( 8 min )

Why Encoding? tokenization. In Natural Language Processing (NLP), we use TensorFlow's Keras API **to easily convert text into sequences of numbers using a **Tokenizer. Why use tensorflow.keras? For smoother experience, especially when using TensorFlow, tools like Google Colab are recommended to avoid installation issues. 1. Tokenisation Explanation: tok=tokenizer() it is an initialisation of tokeniser which will break sentence into words. corp, corpus or paragraph which we will break it. tok.fit_on_texts(corp), it will give index to words. How indexing works in here? the most frequent word get lowest index like 1. print(tok.word_index), it ask for what is word index. 2. Convert text to sequences Problem: What Happens with New Words? When you train a tokenizer on some text, it only builds a vocabulary from those words. Example Without OOV Handling we tokenised the text into word and it have assigned the index. Now try a sentence with a new word "black": Now we have add word black texts_to_sequences() skip the word black. Handle OOV (Out-of-Vocabulary) Words Out of vocabulary words is word that is not present during training fit_on_texts(). Output: {'balck': 1, 'i': 2, 'need': 3, 'coffe': 4, 'we': 5, 'can': 6, 'make': 7, 'it': 8, 'from': 9, 'water': 10} Even though "black" wasn’t in training, it gets index 1 — the reserved OOV token. Limiting the number of words. Let say I don't want whole paragraph I want to limit the words why? because of efficiency if I take corpora (whole paragraph) then to process it will take time. To make it easy we will limit it. tok=Tokenizer(oov_token='balck',num_word=4)  ( 4 min )

"Everyone starts somewhere. I started with confusion, Google searches, and a lot of coffee." But one day, I found the Namaste JavaScript series by Akshay Saini. And that’s when things started to click. He didn’t just teach—he explained why, in a way that felt like a friend walking me through it all. That’s when I decided to dive into Namaste React and Namaste Node.js. ⚛️ Namaste React – Building UIs, Building Confidence But lesson by lesson, project by project, I started seeing it: I built my first component. Then another. I passed props like a pro. I even figured out hooks (well... eventually 😅). There were moments of frustration, but also a lot of "Wow, I actually made that!" And that feeling? Pure gold. 🌐 Namaste Node.js – From Frontend to Full Stack Let me be real: backend scared me. Servers, requests, APIs—it sounded too technical. But this series? It made the complex feel simple. I learned: How servers actually work Building REST APIs from scratch Routing, middleware, and even a bit of MongoDB I started building full-stack apps. Not huge ones, but they were mine. And they worked. ❤️ What I Learned Beyond Code It taught me: To be patient with myself To Google like a ninja That everyone starts as a beginner And that the “hero” isn’t someone who knows everything, but someone who doesn’t stop learning 🚀 To Anyone Starting Now...

I’ve been exploring an idea for a fully automated AI-powered cryptocurrency trading system that could be built entirely using free and publicly available services. The concept combines Groq AI for ultra-fast decision-making, a free crypto news API to analyze real-time market sentiment, and exchange APIs like Binance’s to execute live trades and monitor balances. The system would automatically analyze trends, interpret news, and make informed trading decisions in real time. It would also include a web-based dashboard to display capital status, trade logs, AI insights, and profit and loss — all updated live for full transparency. The goal is to create a highly efficient, intelligent, and low-cost crypto trading setup using freely accessible tools and APIs. It’s still just an idea at this stage, but I believe it has strong potential.

What is a coroutine object? A coroutine is a special kind of function that can pause and resume its execution, allowing asynchronous programming. When you call an async function, it doesn’t run immediately like a regular function. Instead, it returns a coroutine object — essentially a “promise” that it will run when awaited. async def say_hello(): print("Hello!") return "Done" result = say_hello() # This returns a coroutine object, it does NOT execute yet print(result) # # To actually run the coroutine and get the result, you need to await it: output = await say_hello() # Now it runs, prints "Hello!" and returns "Done" print(output) # "Done" Coroutine objects represent tasks that haven’t run yet. You must await them inside an async function to actually execute the code and get the result. If you don’t await and just return the coroutine, it’s like returning a “recipe” instead of the “finished dish.” Your repository functions are async (return coroutine objects). If you return the coroutine itself (without await), FastAPI tries to serialize the coroutine object, which causes errors. You must await those async calls so FastAPI gets the actual data to send in the response.

Overview, Historical Timeline, Problems & Solutions In Python, all data is made of objects. A number is an object. A string is an object. A list is an object. Even functions and classes are objects. Python treats everything as an object so it can store, copy, or link all parts of a program. When you run a program, you give Python values. Python turns those values into objects. The object holds data and also knows what it can do. This is what makes Python flexible and powerful. Python lets you represent all data as objects. name = "Ada" age = 36 Each value here becomes an object. The word name points to a string object. The word age points to a number object. Every object in Python has three parts: identity, type, and value. The identity is like a tag number. It never changes. The type …  ( 7 min )

The SQL INSERT INTO statement is a core part of almost every application—but are you using it efficiently? This guide covers simple syntax, performance pitfalls, and optimization techniques to help you write smarter inserts. Whether you're adding a few rows or importing thousands, these practices will save time and resources. INSERT INTO customers (name, email) VALUES ('Jane', 'jane@example.com'); Insert multiple rows: INSERT INTO customers (name, email) VALUES ('Jane', 'jane@example.com'), ('Mark', 'mark@example.com'); Batch Your Inserts Group records into one INSERT statement. Use Transactions Reduce overhead by committing only once: BEGIN; INSERT INTO ...; COMMIT; Delay Commits Especially for 1000+ row inserts. Bulk Tools Use LOAD DATA INFILE (MySQL) or other tools for large imports. Default Values Set up default values in your schema to simplify inserts. Insert from Another Table INSERT INTO archive_table SELECT * FROM main_table WHERE status = 'closed'; Auto-fill Fields with DEFAULT CREATE TABLE example ( id SERIAL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ); Lock Tables for Heavy Inserts Prevents other queries from interfering. DbVisualizer: A great SQL client with visual tools for editing, running, and debugging INSERT queries. SQL Loader Tools: Try native bulk import tools if you're moving big datasets. Yes—list only the columns you're inserting. LOAD DATA safe for production? Yes, if you're careful about file format and permissions. INSERT with data from other tables? Yes! Combine it with SELECT for mass transfers. If you're not optimizing your INSERT queries, you're leaving performance on the table.

There are 8 Primitive Data Types: byte | 1 byte | Small whole numbers | byte a = 10; | short | 2 bytes | Bit bigger numbers | short b = 1000; | int | 4 bytes | Most common whole numbers | int age = 25; | long | 8 bytes | Huge whole numbers | long stars = 123456789L; | float | 4 bytes | Decimal numbers | float price = 12.5f; | double | 8 bytes | More accurate decimals | double pi = 3.14159; | char | 2 bytes | Single character | char letter = 'A'; | boolean | 1 bit | True or False | boolean isJavaFun = true; | My Personal Suggesion: First start with int for numbers and double for decimals.  ( 3 min )

How to Speak Up and Get Promoted in an IT Company While every company operates differently, the overall mechanics of career growth and salary increases in the IT industry tend to follow similar patterns. At some point, almost every professional — from junior developers to seasoned tech leads — faces the same question: How do I speak up and get recognized if I want to grow or earn more? To move forward successfully, it's important to understand not only your personal goals but also the company's motivations. When a company opens a new position, the primary goal is usually the same: improve business efficiency and profitability. Common reasons include: Filling a specific team role. Increasing team productivity and delivery speed. Reducing pressure on key individuals. Improving product q…  ( 5 min )

When you install or run Python-based tools on Arch Linux — especially from the AUR — you might notice that your system accumulates a lot of __pycache__ directories. These are generated when Python byte-compiles modules, but they aren’t always removed when you uninstall a package. In this short guide, we’ll walk through how to identify and optionally clean up those __pycache__ directories — specifically the ones not owned by any package — and exclude system paths like Flatpak while we're at it. Tools installed via the AUR (like waydroid-scripts-git, for example) might drop files under /opt, /usr/local, or other places. These files (especially .py and __pycache__) might not be tracked by pacman, so even after uninstalling the tool, leftover Python cache directories can remain. __pycache__ Directories Here’s a one-liner that will: Search your system for all __pycache__ directories Skip the Flatpak directory (/var/lib/flatpak) Check whether each is owned by any package Print only the ones that are not owned find / -type d -name '__pycache__' -not -path '/var/lib/flatpak/*' 2>/dev/null | while read dir; do pacman -Qo "$dir" &>/dev/null || echo "Not owned: $dir" done Not owned: /opt/waydroid-scripts/tools/__pycache__ Not owned: /usr/local/lib/python3.11/site-packages/some_tool/__pycache__ __pycache__ directories aren't dangerous, but they can accumulate and clutter your system — especially in directories that aren’t cleaned by package managers. With a few commands, you can find and clean up these leftovers safely, keeping your system neat and under control. Have your own cleanup tricks? Share them in the comments!  ( 3 min )

Introduction Force-pushing in Git (git push --force) is a powerful but dangerous command. It overwrites remote changes without checking if others have pushed new commits, which can lead to lost work. Fortunately, Git provides a safer alternative: git push --force-with-lease. This command ensures you don't accidentally overwrite someone else's changes while still allowing you to rewrite history when needed. In this guide, we'll explore how --force-with-lease works, when to use it, and best practices for avoiding mistakes. --force-with-lease Works Unlike --force, which blindly overwrites the remote branch, --force-with-lease checks if the remote branch has changed since you last fetched it. git push --force → Overwrites remote branch no matter what. git push --force-with-lease → Only o…  ( 6 min )

One of the most powerful features of cloud computing is scalability—and Microsoft Azure makes it incredibly simple with Autoscaling. Whether you're hosting a small web app or a full-scale enterprise platform, you don’t want to be manually adjusting resources every time traffic spikes. That’s where Azure’s autoscaling steps in. Autoscaling means your application can automatically increase or decrease resources based on demand. Instead of overprovisioning (and overpaying) or dealing with performance issues during traffic spikes, you set rules that let Azure do the scaling for you. Azure supports autoscaling for several services: App Services Virtual Machine Scale Sets Azure Kubernetes Service (AKS) Azure Functions In this guide, we’ll focus on App Service autoscaling, since it’s one o…  ( 4 min )

JavaScript’s type coercion and dynamic typing system are full of subtle (and sometimes surprising) behaviors. Understanding these quirks can make you much more confident and effective as a JS developer. Here’s a list of not-so-obvious JavaScript type coercion examples, grouped into categories with explanations: 1. String vs Number Comparison Expression Value Reason '10' < '2' true Lexicographic comparison: '1' comes before '2' '10' < 2 false string '10' is coerced to number 10 '5' == 5 true string '5' is coerced to number 5 '5' === 5 false strict equality, no type coercion Rule: Loose equality (==) allows type coercion. Strict equality (===) does not. 2. Falsy Values JavaScript has falsy values that act like false i…  ( 4 min )

What Are Automated Plug-ins How to Create one The Code Bugs Quick Example Automated plug-ins, I suspect are the future replacement of Business process. Business Process add logic to a Dataverse table beyond a simple calculated column. They can do validation, conditions, update other tables, trigger flows, etc. So a Automated plug-in is linked to a Dataverse table, and on an event (Create, Modify, Delete), the script will run.

Smart contracts are the backbone of decentralized applications (dApps) on the Ethereum blockchain. These contracts are written in Solidity, a statically typed, contract-oriented programming language tailored for Ethereum. One critical yet often overlooked aspect of smart contract development is how contracts are initialized when deployed to the blockchain. This blog post offers a deep dive into the concept of constructors in Solidity, how they work, their purpose, and best practices to keep your contracts secure and efficient. A constructor is a special function in a Solidity contract that is executed only once, at the moment the contract is deployed. Think of it as the setup phase of your smart contract—this is where you define the initial state, set permissions, or configure parameters t…  ( 5 min )

Brute Force Idea: This problem is maybe the easiest HARD problem I have ever solved. I didnt realize first but the bruteforce idea I had was actually the optimal solution. I was always weak at greedy problems, but this one was straightforward. Optimized Strategy: It's a two-pass greedy algorithm. As, the minimum candies a child could have is 1, we can start by giving each child 1 candy. First Pass: We can now iterate from left to right, and if the current child's rat…  ( 4 min )

In over 10 years, I've witnessed all types of interviews: casual conversations, interrogation-like conversations with rapid-fire questions, take-home coding exercises, and the infamous LeetCode exercises. I asked Phind and Copilot to solve an interview exercise. I might or might not have been asked that exercise when applying to a FAANG. Here's the "made-up" problem: You're given a string containing the words "one" and "two", and the symbols "+" and "-" representing a math expression.

It’s Always the Refund It started, as these things always do, with a Slack message from support that began: "This is probably nothing, but…" It never is. Turns out a customer had requested a refund for a $0 order—paid entirely with a promotional code that someone in marketing named “YOLO100.” Our system, ever obedient, generated a pristine digital refund for exactly zero currency units and confidently shoved it into the payment gateway, which replied with the transactional equivalent of a raised eyebrow: "Invalid amount." From there, the trail of confusion expanded outward like a suburban sprawl. Engineering said it shouldn’t be possible. QA said it wasn’t in the test cases. Product said it was “an edge case.” (They always say that, don’t they? Every single cliff we fall off was once c…  ( 6 min )

Why RWAs aren’t the decentralized revolution you think they are Tokenized real-world assets (RWAs) are the new crypto darling. Everyone’s hyped: BlackRock’s onchain, treasuries are getting wrapped, and traditional finance is flirting hard with blockchain. But let’s not get it twisted: RWAs aren’t decentralization. They’re TradFi in a blockchain costume. Here’s the inconvenient truth: Want to buy tokenized real estate? Great. But that token doesn’t give you squat unless a legal entity off-chain honors it. Treasury tokens? Same thing. You’re trusting a fund manager, custodian, or regulatory body to redeem it. It’s not trustless. It’s regulatory theater with a smart contract backend. RWAs are less about empowering users and more about navigating global compliance. It’s not about breaking the system. It’s about bending the rules just enough to extract value while pretending to be futuristic. This isn’t DeFi. It’s just TradFi with faster accounting. Let’s be honest: most RWA projects don’t need a blockchain. They use it for: Token issuance Cap table management Tracking asset flow But these are things spreadsheets and CRMs have done for decades. Putting it onchain doesn’t make it revolutionary — it just makes it buzzword-compliant. Web3 wasn’t about rehypothecating bonds or making banks more efficient. It was about disintermediation. Cutting out the middlemen. Giving power back to users. Trustless systems. RWAs? They reintroduce the middlemen — they just wear hoodies now. Tokenized RWAs sound sexy, but they’re just Wall Street playing dress-up in Web3. Until these assets are truly decentralized — not just onchain — they’ll remain more TradFi than DeFi.  ( 3 min )

Instructions: Create a function finalGrade, which calculates the final grade of a student depending on two parameters: a grade for the exam and a number of completed projects. This function should take two arguments: exam - grade for exam (from 0 to 100); projects - number of completed projects (from 0 and above); This function should return a number (final grade). There are four types of final grades: 100, if a grade for the exam is more than 90 or if a number of completed projects more than 10. Examples(Inputs-->Output): 85, 5 --> 90 55, 3 --> 75 55, 0 --> 0 Thoughts: 1.I use the if/else statement to determine the return of the final grade function of different conditions. Solution: function finalGrade (exam, projects) { if(exam > 90 || projects > 10) return 100; if(exam > 75 & projects >= 5) return 90; if(exam > 50 & projects >= 2) return 75; return 0; } This is a CodeWars Challenge of 8kyu Rank  ( 4 min )

As your app grows or moves into production, small mistakes can snowball into performance bottlenecks, inconsistent data, memory leaks, or even full-on crashes. Not Handling Mongoose Connection Properly The Mistake: A lot of developers connect to MongoDB using something like: mongoose.connect('mongodb://localhost:27017/mydb'); But what if the connection fails?

Primeiro, vamos com calma Antes de tudo, vamos com calma. Sei que esse tipo de afirmação pode gerar problemas de entendimento e até certo favoritismo em relação a tecnologias. Entretanto, precisamos ter em mente as necessidades que nossas ferramentas suprem e por que devemos usá-las. Nos primórdios do desenvolvimento web, quando queríamos conectar e criar ferramentas, não existiam conceitos como micro-frontends, SaaS, microservices ou nada parecido. O mais próximo disso eram aplicações monolíticas, desenvolvidas com stacks que seguiam arquiteturas “quadradas” e bem estabelecidas. Um exemplo clássico é a infame stack LAMP: Linux Apache MySQL PHP Nessa época, era comum seguir a arquitetura MVC (Model-View-Controller), onde: A View apresentava os dados e recebia as entradas dos usuários; O …  ( 5 min )

Hello, fellow Rustaceans (or aspiring ones)!Welcome back to Week 2 of my deep dive into the Rust programming language, and this week I explored compound types and control flow. Here's what I learned, where I got stuck, and how I'm making it make sense. Here's what I tackled: - A. Compound Types: String (and its relationship with &str) Arrays Slices Tuples Structs Enums - B. Control Flow: if/else if/else loop while for loops with iterators Let's dive into how these building blocks are starting to click for me, and how AI is continuing to be a valuable co-pilot. Last week, we dealt with simple numbers and booleans. This week was all about grouping related data and defining my own custom types. String vs. &str This was probably the most nuanced part of learning about text. - String: Owned, …  ( 7 min )

Preventing direct administrative SSH access is a vital component of any defense-in-depth strategy. In this guide, we’ll explore how to restrict privileged users from logging in via SSH using SELinux’s ssh_sysadm_login boolean. This ensures that administrative access is only available after connecting through a restricted, non-privileged jump account — a critical safeguard against misconfiguration and privilege abuse. Overview: Why Restrict Admin SSH Access Step 1: Ensure SELinux is in Enforcing Mode Step 2: Associate Admin Users with sysadm_u Step 3: Disable ssh_sysadm_login Why Not Just Use sshd_config Final Thoughts & Additional Hardening Tips In Part 1 of this series, we set up a restricted jump user — a non-privileged account used to SSH into a Linux server. This user can then escal…  ( 5 min )

135. Candy Difficulty: Hard Topics: Array, Greedy There are n children standing in a line. Each child is assigned a rating value given in the integer array ratings. You are giving candies to these children subjected to the following requirements: Each child must have at least one candy. Children with a higher rating get more candies than their neighbors. Return the minimum number of candies you need to have to distribute the candies to the children. Example 1: Input: ratings = [1,0,2] Output: 5 Explanation: You can allocate to the first, second and third child with 2, 1, 2 candies respectively. Example 2: Input: ratings = [1,2,2] Output: 4 Explanation: You can allocate to the first, second and third child with 1, 2, 1 candies respectively.

AI-Powered Code Generation From Design Streamlining Design-to-Code Conversion AI tools are really changing how we build things, especially when it comes to turning design mockups into actual working code. It used to be that developers would spend a ton of time just translating what a designer made into code. Now, AI can take those designs and spit out production-ready code in a fraction of the time. This means projects can move a lot faster, and teams aren't stuck in that slow back-and-forth process. It's like having a super-fast assistant that understands design and can write code. This shift lets developers focus on more complex problems instead of repetitive coding tasks. It's a big deal for getting products out the door quicker. The whole idea is to cut down on the manual work involved…  ( 7 min )

What is Binary Search Imagine you are playing a game where you try to guess a secret number from 1 to 10, and you have infinite attempts. You can choose random numbers (without repetition)—maybe you will get lucky and guess it on the first try, or it might take you all 10 tries to reach it. Or you can try counting all the numbers in order—1, 2, 3, 4…—this will still take 10 guesses max, but in a more systematic way. But what if you had to guess a number from 1 to 1000, or even 1 to a million? What about 1 to 10²⁰? As the range increases, brute force becomes impractical. Computer scientists faced the same problem: how do you efficiently find something in a huge range? One commonly used solution is binary search. Binary search works by dividing the range in half with each guess, determinin…  ( 4 min )

🚀 Introduction Queues are everywhere — from the print job waiting on your computer to the request processing system of a large-scale web server. But understanding queues isn’t just about putting items in and taking them out — it’s about knowing what kind of queue to use and when. In this post, we’ll explore: ✅ Different types of queues Whether you’re prepping for interviews, building scalable backends, or just exploring Python data structures, this guide is for you. 📦 What is a Queue? A queue is a First-In-First-Out (FIFO) data structure — like a line at the bank. The first person to arrive is the first to be served. But modern systems use variations of queues to solve different problems. That’s what we’ll dive into next. 🧱 Queue Types & Use Cases 🎯 Simple Queue • Behavior: FIFO 🔁 Circular Queue • Behavior: FIFO with a circular buffer (head connects to tail) ⏫ Priority Queue • Behavior: Elements are served based on priority 🔄 Deque (Double-Ended Queue) • Behavior: Can insert/remove from both ends 🤝 Concurrent Queue • Behavior: Thread-safe queue for multi-threaded systems 🧵 Curious about thread-safe? It means multiple threads can access the queue without data corruption or race conditions. 📩 Message Queue (Job Queue) • Behavior: Asynchronous communication between producers & consumers 🛠 Practical Examples & Code Each queue is implemented in clean Python code in this GitHub repository: queue-patterns GitHub Repo All implementations include: 📍 Why This Matters Too often, people use one kind of queue for everything. Understanding which queue fits which problem leads to: Mastering queues isn’t just for computer science students — it’s for any developer working on backends, automation, data processing, or system design. 🙌 Found this helpful?
